Abstract

A pixel electrode and a display panel are provided. The pixel electrode includes a sub-pixel region and a main pixel region arranged at intervals. The sub-pixel region includes a first sub-pixel region and a second sub-pixel region, wherein a receiving chamber is formed between the first sub-pixel region and the second sub-pixel region, and the main pixel region is disposed in the receiving chamber.

First claim

What is claimed is:

1. A pixel electrode, comprising:
a sub-pixel region and a main pixel region arranged at intervals, wherein the sub-pixel region comprises a first sub-pixel region and a second sub-pixel region, wherein a receiving chamber is formed between the first sub-pixel region and the second sub-pixel region, and wherein the main pixel region is defined in the receiving chamber; and
a first body portion and a second body portion, wherein the first body portion is intersected with the second body portion, and the first body portion and at least a portion of the second body portion are disposed in the main pixel region;
wherein the main pixel region comprises a first sub-region, a second sub-region, and a third sub-region, the first sub-region is disposed above the second body portion, the second sub-region is disposed below the second body portion, and the third sub-region comprises the second body portion, a plurality of branch portions, and a peripheral portion, wherein one end of one of the plurality of branch portions is connected to the second body portion, and the peripheral portion surrounds the second body portion and the plurality of branch portions.

2. The pixel electrode according to claim 1 , wherein the first sub-pixel region and the second sub-pixel region both comprise a main sub-region and a secondary sub-region, the main sub-region is connected to a corresponding secondary sub-region and disposed above the second body portion, and the secondary sub-region is disposed below the second body portion.

3. The pixel electrode according to claim 1 , wherein at least a part of the second body portion is positioned in the sub-pixel region.

4. The pixel electrode according to claim 3 , wherein the second body portion comprises a first sub-portion and a second sub-portion, the first sub-portion is positioned in the first sub-pixel region, and the second sub-portion is positioned in the second sub-pixel region.

5. The pixel electrode according to claim 4 , wherein the second body portion further comprises a third sub-portion, and the third sub-portion is positioned in the main pixel region.

6. The pixel electrode according to claim 1 , wherein the main pixel region is symmetrical with respect to the first body portion or the second body portion, and the first sub-pixel region and the second sub-pixel region are symmetrical with respect to the first body portion.

7. The pixel electrode according to claim 1 , wherein an area of the main pixel region is less than or equal to a sum of an area of the first sub-pixel region and an area of the second sub-pixel region.

8. The pixel electrode according to claim 1 , wherein an area of the first sub-pixel region is equal to an area of the second sub-pixel region.

9. The pixel electrode according to claim 8 , wherein an area of the main pixel region is equal to the area of the first sub-pixel region.

10. A display panel comprising a pixel electrode, wherein the pixel electrode comprises:
a sub-pixel region and a main pixel region arranged at intervals, wherein the sub-pixel region comprises a first sub-pixel region and a second sub-pixel region, wherein a receiving chamber is formed between the first sub-pixel region and the second sub-pixel region, and wherein the main pixel region is defined in the receiving chamber; and
a first body portion and a second body portion, wherein the first body portion is intersected with the second body portion, and the first body portion and at least a portion of the second body portion are disposed in the main pixel region;
wherein the main pixel region comprises a first sub-region, a second sub-region, and a third sub-region, the first sub-region is disposed above the second body portion, the second sub-region is disposed below the second body portion, and the third sub-region comprises the second body portion, a plurality of branch portions, and a peripheral portion, wherein one end of one of the plurality of branch portions is connected to the second body portion, and the peripheral portion surrounds the second body portion and the plurality of branch portions.

11. The display panel according to claim 10 , wherein the first sub-pixel region and the second sub-pixel region both comprise a main sub-region and a secondary sub-region, the main sub-region is connected to a corresponding secondary sub-region and disposed above the second body portion, and the secondary sub-region is disposed below the second body portion.
