Method of fabricating an LCD, including steps of forming a color filter by pressing with a soft mold
View Patent ↗There is disclosed a liquid crystal display panel that is adaptive for simplifying its process and reducing its cost by performing a patterning process without using a photolithography process, and a fabricating method thereof. A liquid crystal display panel according to an embodiment of the present invention includes a color filter which is formed by a press forming by a soft mold; and a black matrix to divide the color filter by the cell.
1. A fabricating method of a liquid crystal display panel, comprising:
forming a black matrix on a substrate; and
forming a color filter by pressing a color resin with a soft mold after the color resin is applied to the substrate having the black matrix, wherein forming the color filter includes:
forming a first color layer corresponding to a first groove by pressing a first color resin with a first soft mold having the first groove after forming the first color resin on the substrate where the black matrix is formed;
forming a second color layer corresponding to a second groove by pressing a second color resin with a second soft mold having the second groove, which has wider width than the first groove, after forming the second color resin on the substrate where the first color layer is formed; and
forming a third color layer corresponding to a third groove by pressing a third color resin with a third soft mold having the third groove, which is wider than the second groove, after forming the third color resin on the substrate where the second color layer is formed.
2. The fabricating method according to claim 1 , wherein the color resin is a liquefied material where a resist material is mixed with at least any one resin among resins which realize first to third colors.
3. The fabricating method according to claim 1 , wherein the first color layer is located so that two color layers realizing the same color are close to each other, the second color layer covers the first color layer, and the third color layer covers the first color layer and the second color layer.
4. The fabricating method according to claim 1 , further comprising:
removing a part of the first to third color layers by at least any one process of ashing And polishing.
5. The fabricating method according to claim 1 , further comprising:
forming a common electrode on a substrate where the color filter is formed; and
forming a spacer on the substrate where the common electrode is formed.
