Abstract

The present invention provides a display panel and a display device, the display panel includes a first substrate; and a second substrate disposed opposite to the first substrate; and further includes two pixel layers, respectively a first pixel layer and a second a pixel layer; the first pixel layer is disposed on a surface of one side of the first substrate; and the second pixel layer is disposed on a surface of the second substrate facing the first pixel layer. The technical effect of the present invention is to improve the pixel resolution of the display panel.

First claim

What is claimed is:

1. A display panel, comprising:
a first substrate;
a second substrate disposed opposite to the first substrate;
two pixel layers comprising a first pixel layer and a second pixel layer, wherein the first pixel layer is disposed on a surface of one side of the first substrate, and the second pixel layer is disposed on a surface of the second substrate facing the first pixel layer;
a first transparent electrode disposed between the first substrate and the first pixel layer; and
a second transparent electrode disposed on a surface of the first pixel layer away from a side of the first transparent electrode;
a third transparent electrode layer disposed on a surface of the second pixel layer away from a side of the second substrate;
a reflective electrode disposed on a surface of the second pixel layer away from a side of the third transparent electrode layer; and
a mirror disposed between the second substrate and the reflective electrode.

2. The display panel according to claim 1 , wherein the pixel layers each includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

3. The display panel according to claim 2 , wherein the red sub-pixel is square, the green sub-pixel is square, and the blue sub-pixel is rectangular.

4. The display panel according to claim 2 , wherein a side length of the red sub-pixel is equivalent to a side length of the green sub-pixel.

5. The display panel according to claim 2 , wherein a sum of areas of the red sub-pixel and the green sub-pixel is equivalent to an area of the blue sub-pixel.

6. The display panel according to claim 1 , wherein two or more red sub-pixels and two or more green sub-pixels of the same pixel layer are disposed in a same line; a green sub-pixel is disposed between any two adjacent red sub-pixels, and two or more blue sub-pixels of the same pixel layer are disposed in a same line.

7. The display panel according to claim 2 , wherein the two adjacent red sub-pixel and green sub-pixel of one pixel layer are disposed opposite to the blue sub-pixel of another pixel layer.

8. A display device, comprising the display panel of claim 1 .
