Abstract

Embodiments of the present disclosure provide a display panel and a display device. The display panel of the present disclosure comprises matrix-arranged pixel units and a grating provided at a light-exiting surface side of the display panel. The grating comprises light blocking zones and light transmission zones provided alternately in a row, and the light blocking zones and light transmission zones are provided alternately in the order of light blocking zone and light transmission zone in one of two adjacent rows and in the order of light transmission zone and light blocking zone in the other of the two adjacent rows, wherein each of at least one light blocking zone blocks completely a pixel unit. The display panel of the disclosure can solve the problem of the moire phenomenon which is caused by the overlap of directions of the light blocking zones of the grating and the black matrix of the existing display panel. In addition, the display effect of the display panel of the disclosure is better.

Claims

1. A display panel comprising matrix-arranged pixel units and a grating provided at a light-exiting surface side of the display panel, wherein the grating comprises light blocking zones and light transmission zones provided alternately in a row, and the light blocking zones and light transmission zones are provided alternately in the order of light blocking zone and light transmission zone in one of two adjacent rows and in the order of light transmission zone and light blocking zone in the other of the two adjacent rows, wherein

each of at least one light blocking zone blocks completely a pixel unit.

2. The display panel according to claim 1, the area of each light blocking zone is equal to the area of each pixel unit.

3. The display panel according to claim 1, wherein the area of each light blocking zone is equal to the area of each light transmission zone.

4. The display panel according to claim 1, wherein each light blocking zone blocks completely one pixel unit.

5. The display panel according to claim 1, wherein the area of each light blocking zone is greater than the area of each light transmission zone.

6. The display panel according to claim 5, wherein the area of each light blocking zone is two times of the area of each light transmission zone.

7. The display panel according to claim 1, wherein one of two adjacent light blocking zones in a row blocks completely a pixel unit, the other one blocks a part of each of the two adjacent pixel units.

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