Method of producing liquid crystal display element

Claim 1

A method of producing a liquid crystal display element having a first electrode substrate and a second electrode substrate bonded to the first electrode substrate with a gap therebetween, said method comprising the steps of: holding said first electrode substrate on one of an upper and lower jig of an alignment apparatus, said lower jig having a holding pattern; holding said second electrode substrate on the other of said upper and lower jig of said alignment apparatus; relatively moving said upper and lower jigs of said alignment apparatus so as to align said first and second electrodes with each other; superposing said two substrates together with substantially no slippage therebetween through the intermediary of a photo-settable sealing agent with a gap therebetween pressing said two substrates together through said sealing agent to obtain a temporarily assembled liquid crystal display element; fixing said temporarily assembled liquid crystal display element to a fixing base which is placed in a case and which has the same holding pattern as that of said lower jig in said alignment apparatus; placing a transparent plastic sheet on said temporarily assembled liquid crystal display element; evacuating the space between said fixing base and said plastic sheet to produce a vacuum so as to press said temporarily assembled liquid crystal display element under vacuum; and photo-setting said sealing agent press-bonded to said substrates to obtain a liquid crystal display element.

Claim 2

A method of producing a liquid crystal display element having a first electrode substrate and a second electrode substrate bonded to the first electrode substrate with a gap therebetween, said method comprising the steps of: holding said first electrode substrate on one of an upper and lower jig of an alignment apparatus, said lower jig having a holding pattern; holding said second electrode substrate on the other of said upper and lower jig of said alignment apparatus; relatively moving said upper and lower jigs of said alignment apparatus so as to align said first and second electrodes with each other; superposing said two substrates together with substantially no slippage therebetween through the intermediary of a photo-settable sealing agent with a gap therebetween pressing said two substrates together through said sealing agent to obtain a temporarily assembled liquid crystal display element; fixing said temporarily assembled liquid crystal display element to a fixing base which is placed in a case and which has the same holding pattern as that of said lower jig in said alignment apparatus; placing a transparent plastic sheet on said temporarily assembled liquid crystal display element; evacuating the space between said fixing base and said plastic sheet to produce a vacuum so as to press said temporarily assembled liquid crystal display element under vacuum; and photo-setting said sealing agent press-bonded to said substrates to obtain a liquid crystal display element.

Claim 3

A method of producing liquid crystal display element having a first electrode substrate and a second electrode substrate bonded to the first electrode substrate with a gap therebetween, said method comprising the steps of: arranging a first electrode substrate, on which at least a photo-settable sealing agent containing gap materials is applied in a pattern, opposite to a second electrode substrate; aligning said two substrates with each other through the use of an alignment jig apparatus; superposing said two substrates together with substantially no slippage therebetween through the intermediary of a photo-settable sealing agent with a gap therebetween; pressing said two substrates together to obtain a temporarily assembled liquid crystal display element; fixing said temporarily assembled liquid crystal display element on a fixing base in a case which is interposed between a feed roll and a take-up roll for a transparent plastic sheet; bringing said plastic sheet near said temporarily assembled liquid crystal display element; evacuating the space between said fixing base and said plastic sheet to produce a vacuum so as to press said temporarily assembled liquid crystal display element together under vacuum; and photo-setting said sealing agent press-bonded to said substrates to obtain a liquid crystal display element; rotating said take-up roll so as to feed said plastic sheet to prepare for pressing a new temporarily assembled liquid crystal display element.

Claim 4

A method of producing liquid crystal display element having a first electrode substrate and a second electrode substrate bonded to the first electrode substrate with a gap therebetween, said method comprising the steps of: arranging a first electrode substrate, on which at least a photo-settable sealing agent containing gap materials is applied in a pattern, opposite to a second electrode substrate; aligning said two substrates with each other through the use of an alignment jig apparatus; superposing said two substrates together with substantially no slippage therebetween through the intermediary of a photo-settable sealing agent with a gap therebetween; pressing said two substrates together to obtain a temporarily assembled liquid crystal display element; fixing said temporarily assembled liquid crystal display element on a fixing base in a case which is interposed between a feed roll and a take-up roll for a transparent plastic sheet; bringing said plastic sheet near said temporarily assembled liquid crystal display element; evacuating the space between said fixing base and said plastic sheet to produce a vacuum so as to press said temporarily assembled liquid crystal display element together under vacuum; and photo-setting said sealing agent press-bonded to said substrates to obtain a liquid crystal display element; rotating said take-up roll so as to feed said plastic sheet to prepare for pressing a new temporarily assembled liquid crystal display element.

Claim 5

A method of producing a liquid crystal display element having a first electrode substrate and a second electrode substrate bonded to the first electrode substrate with a gap therebetween, said method comprising the steps of: aligning said first and second substrates with each other using an aligning jig apparatus; superposing said two substrates with substantially no slippage therebetween through the intermediary of a photo-settable sealing agent with a gap therebetween; pressing said two substrates to obtain a temporarily assembled liquid crystal display element; fixing said temporarily assembled liquid crystal display element on a fixing base in a case; bringing a transparent plastic sheet near said temporarily assembled liquid crystal display element; gradually reducing pressure in said case to about 160 torr in the space between said fixing base and said plastic sheet, then to 1 torr or less in two or more stages or at two or more pressure reduction rates, to produce a vacuum so as to press said temporarily assembled liquid crystal display element under vacuum; and photo-setting said sealing agent.

Claim 6

A method of producing a liquid crystal display element having a first electrode substrate and a second electrode substrate bonded to the first electrode substrate with a gap therebetween, said method comprising the steps of: aligning said first and second substrates with each other using an aligning jig apparatus; superposing said two substrates with substantially no slippage therebetween through the intermediary of a photo-settable sealing agent with a gap therebetween; pressing said two substrates to obtain a temporarily assembled liquid crystal display element; fixing said temporarily assembled liquid crystal display element on a fixing base in a case; bringing a transparent plastic sheet near said temporarily assembled liquid crystal display element; gradually reducing pressure in said case to about 160 torr in the space between said fixing base and said plastic sheet, then to 1 torr or less in two or more stages or at two or more pressure reduction rates, to produce a vacuum so as to press said temporarily assembled liquid crystal display element under vacuum; and photo-setting said sealing agent.
