Abstract

A liquid crystal display panel and a method of fabricating the same are capable of simplifying a fabricating process and forming a spacer at a desired location. A liquid crystal display panel according to the present invention includes: a black matrix formed on an upper substrate; a color pattern having at least one hole on the black matrix; and a spacer protruding from the at least one hole.

Claims (27)

1. A liquid crystal display panel comprising:

a black matrix on an upper substrate;

a color pattern having at least one hole on the black matrix;

a spacer protruding from the at least one hole, and

a color filter at each area partitioned by the black matrix.

2. The liquid crystal display panel of claim 1 , wherein the color pattern has a structure having at least two layers.

3. The liquid crystal display panel of claim 2 , wherein the color pattern is formed by stacking a red color pattern, a green color pattern and a blue color pattern.

4. The liquid crystal display panel of claim 2 , wherein a width of the color pattern narrows from an uppermost layer to a lowermost layer.

5. The liquid crystal display panel of claim 2 , wherein the color pattern has an identical width in each layer.

6. The liquid crystal display panel of claim 1 , wherein the color pattern has a width less than that of the black matrix.

7. The liquid crystal display panel of claim 1 , further comprising a common electrode located between the color filter and the spacer.

8. The liquid crystal display panel of claim 1 , wherein the spacer is formed by using an inkjet system.

9. A method of fabricating a liquid crystal display panel comprising:

forming a black matrix on a substrate;

forming a color filter at each area partitioned by the black matrix;

forming a color pattern having at least one hole on the black matrix; and

forming a spacer protruding from the at least one hole.

10. The method of claim 9 , wherein the color pattern has a structure having at least two layers.

11. The method of claim 10 , wherein a width of the color pattern narrows from an uppermost layer to a lowermost layer.

12. The method of claim 10 , wherein the color pattern has an identical width in each layer.

13. The method of claim 9 , wherein the step of forming the color pattern includes:

forming a red color pattern on the black matrix;

forming a green color pattern on the red color pattern; and

forming a blue color pattern on the green color pattern.

14. The method of claim 9 , wherein the color pattern is formed to have a width less than that of the black matrix.

15. The method of claim 9 , further comprising forming a common electrode located between the color filter and the spacer.

16. The method of claim 9 , wherein forming a spacer includes dispensing spacer material using an inkjet system.
