Method of forming color filter layer and method of fabricating liquid crystal display device using the same

A method of forming a color filter layer, comprising:

• attaching a first mold having at least a first groove on a substrate and forming a first channel by the first groove and the substrate;
• filling the first channel with a first color resin for a first time to form a first sub-color filter after attaching the first mold on the substrate;
• attaching a second mold having at least a second groove on the substrate and forming a second channel by the second groove, the first sub-color filter and the substrate;
• filling the second channel with a second color resin for a second time to form a second sub-color filter after attaching the second mold on the substrate, 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 filling the second channel with the second color resin;
• attaching a third mold having at least a third groove on the substrate and forming a third channel by the third groove, the first sub-color filter, the second color-filter and the substrate;
• and
• filling the third channel with a third color resin for a third time to form a third sub-color filter after attaching the third mold on the substrate, 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 filling the third channel with the third color resin wherein the second groove has a volume greater than the first groove and smaller than the third groove.

A method of fabricating a color filter substrate for a liquid crystal display device, comprising:

• forming a black matrix on a substrate having first, second and third regions;
• attaching a first mold having a first groove on the substrate, the first groove corresponding to the first region, wherein the first groove and the substrate constitute a first channel;
• filling the first channel with a first color resin for a first time to form a first sub-color filter after attaching the first mold on the substrate;
• curing the first sub-color filter;
• detaching the first mold from the substrate;
• attaching a second mold having a second groove on the substrate, the second groove corresponding to the first and second regions, wherein the second groove, the first sub-color filter and the substrate constitute a second channel;
• filling the second channel with a second color resin for a second time to form a second sub-color filter after attaching the second mold on the substrate, the first sub-color filter used as one sidewall of the second channel and the second mold used as the other sidewall of the third channel while filling the second channel with the second color resin;
• curing the second sub-color filter;
• detaching the second mold from the substrate;
• attaching a third mold having a third groove on the substrate, the third groove corresponding to the first, second and third regions, wherein the third groove, the first sub-color filter, the second sub-color filter and the substrate constitute a third channel, and wherein the second groove has a volume greater than the first groove and smaller than the third groove;
• filling the third channel with a third color resin for a third time to form a third sub-color filter after attaching the third mold on the substrate, 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 filling the third channel with the third color resin;
• curing the third sub-color filter;
• detaching the third mold from the substrate;
• and
• forming a common electrode on a color filter layer including the first, second and third sub-color filters.
