Abstract

A liquid crystal display panel and a liquid crystal display are disclosed. The liquid crystal display panel includes a color film substrate and an array substrate disposed opposite each other, wherein the array substrate includes a pixel electrode, a color resistance layer, and a thin film transistor, the color resistance layer is provided with a through hole, a drain of the thin film transistor is connected with the pixel electrode through the through hole, and a region corresponding to the through hole is provided with a spacer for separating liquid crystal molecules in the region where the through hole is located from liquid crystal molecules in a region where the electrodes are located.

First claim

What is claimed is:

1. A liquid crystal display panel, comprising:
a color film substrate and an array substrate disposed facing each other, wherein the array substrate includes a main pixel electrode, a color resistance layer, and a thin film transistor, wherein the main pixel electrode is separated from the thin film transistor, the main pixel electrode does not overlap the thin film transistor, the color resistance layer is provided with a through hole, the main pixel electrode is connected with a drain of the thin film transistor via a connector penetrating through the through hole, and a spacer separates liquid crystal molecules which are in and directly above the through hole from liquid crystal molecules which are directly on and above the main pixel electrode.

2. The liquid crystal display panel as claimed in claim 1 , wherein the spacer is disposed on a side of the color film substrate corresponding to a periphery of the through hole and facing the pixel electrode.

3. The liquid crystal display panel as claimed in claim 2 , wherein the spacer has a straight bar-like structure.

4. The liquid crystal display panel as claimed in claim 2 , wherein the spacer has a structure of a curved surface.

5. The liquid crystal display panel as claimed in claim 1 , wherein the spacer is a hollow columnar structure surrounding the through hole, and an inner diameter of the cylindrical structure is larger than a diameter of the through hole.

6. The liquid crystal display panel as claimed in claim 1 , wherein the spacer is a hollow columnar structure surrounding the through hole, an area of an top surface of the columnar structure is different from an area of a bottom surface of the columnar structure, and a minimum inner diameter of the columnar structure is larger than a diameter of the through hole.

7. The liquid crystal display panel as claimed in claim 1 , wherein the spacer is a box-shaped structure surrounding a periphery of the through-hole.

8. The liquid crystal display panel according to claim 7 , wherein the box-shaped structure is defined by four sides, and the four sides include the side facing the pixel electrode and the other three sides each having a hollow structure.

9. The liquid crystal display panel as claimed in claim 1 , wherein the spacer is disposed on the array substrate.

10. A liquid crystal display panel comprising:
a color film substrate and an array substrate disposed facing each other, wherein the array substrate includes a main pixel electrode, a color resistance layer, and a thin film transistor, wherein the main pixel electrode is separated from the thin film transistor, the main pixel electrode does not overlap the thin film transistor, the color resistance layer is provided with a through hole, the main pixel electrode is connected with a drain of the thin film transistor via a connector penetrating through the through hole, and a spacer separates liquid crystal molecules which are in and directly above the through hole is located from liquid crystal molecules which are directly on and above the main pixel electrode;
wherein the spacer is disposed on a side of the color film substrate corresponding to a periphery of the through hole and facing the pixel electrode;
wherein the spacer is a box-shaped structure surrounding a periphery of the through-hole; and
wherein the box-shaped structure is defined by four sides, and the four sides include the side facing the pixel electrode and the other three sides each having a hollow structure.

11. A liquid crystal display comprising: a backlight module and a liquid crystal display panel as claimed in claim 1 .
