Forming a topcoat for liquid crystal display devices having plastic substrates using UV light and temperatures less than 200amp;deg; C.

摘要

A liquid crystal display device has a pair of transparent plastic substrates. Electrodes formed on an inner side of each substrate is covered with a topcoat and electrically and physically protected thereby. This topcoat has been formed by first applying a silica coating ink (e.g., MOF Si film or Ti-Si film made by Tokyo Oka K.K.) over the electrodes as a material of the topcoat, then irradiating the silica coating ink with ultraviolet light to evaporate a high-boiler solvent in the silica coating ink, and then baking the silica coating ink at a temperature of 200° C. or lower.
