Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 87 words
A method for manufacturing a liquid crystal display in which a space between a first substrate having switching elements and electrodes connected to the elements and a second substrate facing the first substrate is sealed with a sealing member, and then a liquid crystal material is injected into said space, comprising the steps of: electrically connecting said electrodes of said first substrate to a grounding portion of a device used for forming said sealing member; and forming said sealing member on said first substrate with said device.
Claim 2
Independent Claim 87 words
A method for manufacturing a liquid crystal display in which a space between a first substrate having switching elements and electrodes connected to the elements and a second substrate facing the first substrate is sealed with a sealing member, and then a liquid crystal material is injected into said space, comprising the steps of: electrically connecting said electrodes of said first substrate to a grounding portion of a device used for forming said sealing member; and forming said sealing member on said first substrate with said device.
Claim 3
Dependent Claim 25 words
A method of manufacturing a liquid crystal display as claimed in claim 1, wherein said device for forming said sealing member is a screen printer.
Claim 4
Dependent Claim 30 words
A method of manufacturing a liquid crystal display as claimed in claim 2, wherein said electrodes of said first substrate are short-circuited with a printing stage of said screen printer.
