Patent ID: 8012385

Claim:
A method of forming a color filter layer, comprising: forming a first sub-color filter on a substrate by placing a first mold having at least a first groove on the substrate such that the first groove and the substrate constitute a first channel and injecting a first color resin into the first channel for a first time, the substrate including first, second and third regions and the first groove corresponding to the first region, wherein injecting the first color resin into the first channel is performed after placing the first mold on the substrate; forming a second sub-color filter on the substrate by placing a second mold having at least a second groove on the substrate such that the second groove, the first sub-color filter and the substrate constitute a second channel and injecting a second color resin into the second channel for a second time, the second groove corresponding to the first and second regions, the first sub-color filter used as one sidewall of the second channel and the second mold used as the other sidewall of the second channel while injecting the second color resin, wherein injecting the second color resin into the second channel is performed after placing the second mold on the substrate; and forming a third sub-color filter on the substrate by placing a third mold having at least a third groove on the substrate such that the third groove, the first sub-color filter, the second sub-color filter and the substrate constitute a third channel and injecting a third color resin into the third channel for a third time, the third groove corresponding to the first, second and third regions, the second sub-color filter used as one sidewall of the third channel and the third mold used as the other sidewall of the third channel while injecting the third color resin, wherein injecting the third color resin into the third channel is performed after placing the third mold on the substrate wherein the second groove has a volume greater than the first groove and smaller than the third groove.
