Liquid crystal display device
View Patent ↗A LCD and a fabrication process is presented. An upper substrate is coincidently formed with a red, a green and a blue color filters using phase separation. A compound containing a photopolymeric color filter resin and a liquid crystal are coated on an array substrate and then photopolymerized after formation of the array substrate. A seed layer may be provided on the substrate before the compound is applied. Polymerization of the color filter resin permits simultaneous formation of the upper, color filter substrate and liquid crystal layer.
