摘要： An electrode plate structure for a liquid crystal color display is produced by forming a color filter layer of a photosensitive polyamide resin containing a colorant dispersed therein; disposing a protective layer of a photosensitive polyamide resin on the color filter layer; forming an ITO (indium-tin-oxide) film on the protective layer, preferably at an elevated temperature of at most 270.degree. C.; post-annealing the ITO film at a temperature of 200.degree.-300.degree. C. for improving the crystallinity of the ITO film suitable for etching; and selectively etching the ITO film patternwise with an etchant of hydroiodic acid or a hydroiodic acid-ferric chloride aqueous solution mixture to leave an ITO electrode pattern.

摘要： A liquid crystal device is formed by disposing a liquid crystal between a pair of oppositely disposed electrodes, at least one of which has a laminated structure including a first layer of ITO (indium tin oxide), a second layer of Mo (molybdenum) or its alloy, and a third layer of Al (aluminum) or its alloy, disposed in the order named. Because of the Mo-based second layer, the ITO layer is protected during development of a photoresist layer formed on the Al-based third layer even if some pinholes are present in the Al-based third layer. The Mo-based second layer can be etched by an etchant for the Al-based third layer so that the entire process is not complicated because of the provision of the Mo-based second layer.

摘要： A large-sized liquid crystal panel uniformly filled with a liquid crystal material may be produced through a process including the steps of: fixing a pair of substrates with a sealing member disposed therebetween to form a blank panel having an injection port, reducing a pressure within the panel, applying a liquid crystal material onto the injection port, heating the liquid crystal material to its isotropic temperature, injecting the liquid crystal material into the panel under a pressure, and filling the panel with the liquid crystal material under heating and pressurization from the injection port toward the panel inside. The pressure within the panel before the injection is reduced at a rate not exceeding 25 torr/min. The pressure for injection is increased at varying rates, e.g., with an intermediate constant pressure period. In the filling step, a portion of the liquid crystal material near the injection port is held in its isotropic phase and the liquid crystal material except for the portion is transformed at least once into a smectic phase.
