Abstract
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.
Claims5
A liquid crystal device, comprising:
- a pair of oppositely disposed substrates and a liquid crystal disposed between the substrates, one of the substrates further comprising in the order named (i) a color filter layer comprising a photosensitive polyamide resin having a colorant dispersed therein, (ii) a protective layer comprising a photosensitive polyamide resin, (iii) an indium-tin oxide film, and (iv) an alignment control film.
