Production of case for luquid crystal cell

Abstract

Abstract PURPOSE: To make the uniformalization of the thickness of liquid crystal easy by spraying the liquid dispersed with fine particles of spacer material onto the surface of one substrate treated by liquid crystal orientation and adhering a pair of the substrates under pressure after allowing this liquid to evaporate. CONSTITUTION: A liquid crystal orientation layer comprising polyimide resin is provided on the surface on the conductive film side of a glass substrate having a patterned transparent conductive film on the surface and a sealing wall having a liquid crystal lead-in hole is provided on the peripheral part of the surface on this orientation film side to make a base material 1. With the orientation layer side thereof being directed upward, this material is fed on a belt conveyor 2 in the arrow direction. On the other hand, a case 3 containing the mixed liquid of ethylene tetrafluoride as a dispersing meduim which dose not damage the orientation layer and glass fibers as fine particles of spacer material is vibrated and agitated by an ultrasonic vibrator 5 by way of water 4, thence this mixed liquid is sprayed by a sprayer 6 onto the base material 1. After this sprayed liquid is allowed to evaporate, a pair of the base materilals is adhered under pressure, whereby the thickness of the liquid crystal may be easily uniformalized.
