Abstract

A thin-film transistor array substrate and a liquid crystal display panel are provided. The thin-film transistor array substrate includes a substrate, a thin-film transistor array, a color resisting layer and an alignment film The substrate includes a first surface and a second surface opposing to each other. The first surface has a revealing region and a non-revealing region surrounding the revealing region. The thin-film transistor array is arranged on the first surface of the substrate. The color resisting layer is arranged on the thin-film transistor array and has a trench located correspondingly to the non-revealing region. The alignment film is arranged on the color resisting layer.

First claim

What is claimed is:

1. A thin-film transistor array substrate, comprising:
a substrate comprising a first surface and a second surface opposing to each other, the first surface having a revealing region and a non-revealing region surrounding the revealing region;
a thin-film transistor array arranged on the first surface of the substrate;
a color resisting layer which is arranged on the thin-film transistor array and comprises a trench located correspondingly to the non-revealing region; and
an alignment film arranged on the color resisting layer.

2. The thin-film transistor array substrate according to claim 1 , wherein the color resisting layer comprises at least one trench.

3. The thin-film transistor array substrate according to claim 1 , wherein the color resisting layer comprises a plurality of trenches that are parallel with each other.

4. The thin-film transistor array substrate according to claim 1 , wherein the color resisting layer comprises a plurality of trenches that are formed in a grid pattern.

5. A liquid crystal display panel, comprising a thin-film transistor array substrate which comprises:
a first substrate comprising a first surface and a second surface opposing to each other, the first surface having a revealing region and a non-revealing region surrounding the revealing region;
a thin-film transistor array arranged on the first surface of the first substrate;
a color resisting layer which is arranged on the thin-film transistor array and comprises a first trench located correspondingly to the non-revealing region; and
a first alignment film arranged on the color resisting layer.

6. The liquid crystal display panel according to claim 5 , wherein the color resisting layer comprises at least one first trench.

7. The liquid crystal display panel according to claim 5 , wherein the color resisting layer comprises a plurality of first trenches that are parallel with each other.

8. The liquid crystal display panel according to claim 5 , wherein the color resisting layer comprises a plurality of first trenches that are formed in a grid pattern.

9. The liquid crystal display panel according to claim 5 further comprising a second substrate, the second substrate comprising a third surface and a fourth surface opposing to each other, the third surface which is closer to the first surface in comparison with the fourth surface having a black matrix layer, the black matrix layer having a second trench opposing to the first trench.

10. The liquid crystal display panel according to claim 9 , wherein the second trench faces directly to the first trench or interlaces with the first trench.
