Abstract

A display panel and a display device are provided. The display panel includes an array substrate, a color filter substrate arranged opposite to the array substrate, and an electrically conductive first connector. A common electrode is arranged on the array substrate, and a black matrix layer is arranged on a side of the color filter substrate facing the array substrate, and the first connector electrically connects at least a part of the black matrix layer to the common electrode.

First claim

What is claimed is:

1. A display panel, comprising:
an array substrate, a common electrode being arranged on the array substrate;
a color filter substrate arranged opposite to the array substrate, a black matrix layer being arranged on a side of the color filter substrate facing the array substrate;
a first connector, the first connector being electrically conductive and electrically connecting at least a part of the black matrix layer to the common electrode; and
a second connector, the second connector being electrically conductive,
wherein a low level signal terminal is further arranged on the array substrate, a transparent antistatic layer is arranged on a side of the color filter substrate away from the array substrate, the second connector electrically connects at least a part of the antistatic layer to the low level signal terminal, and the black matrix layer is separated and insulated from the second connector, and
a portion of the array substrate extends beyond an edge of the color filter substrate and forms a binding region, and both the first connector and the second connector are arranged on the binding region.

2. The display panel according to claim 1 , wherein the black matrix layer is divided into a first black matrix portion and a second black matrix portion separated and insulated from each other, the second black matrix portion is adjacent to the second connector, and the first back matrix portion is electrically connected to the first connector.

3. The display panel according to claim 1 , wherein a first notch is formed in the black matrix layer, and the first notch is adjacent to the second connector.

4. The display panel according to claim 1 , wherein the antistatic layer is divided into a first antistatic portion and a second antistatic portion separated and insulated from each other, the first antistatic portion is adjacent to the first connector, and the second antistatic portion is electrically connected to the second connector.

5. The display panel according to claim 1 , wherein a second notch is formed in the antistatic layer, and the second notch is adjacent to the first connector.

6. The display panel according to claim 1 , wherein the first connector and the second connector are arranged at two ends of the binding region, respectively.

7. The display panel according to claim 1 , wherein both the first connector and the second connector are made of a silver conductive adhesive.

8. A display device, comprising:
the display panel according to claim 1 .

9. The display panel according to claim 2 , wherein both the first connector and the second connector are made of a silver conductive adhesive.

10. The display device according to claim 8 , wherein the black matrix layer is divided into a first black matrix portion and a second black matrix portion separated and insulated from each other, the second black matrix portion is adjacent to the second connector, and the first back matrix portion is electrically connected to the first connector.

11. The display device according to claim 8 , wherein a first notch is formed in the black matrix layer, and the first notch is adjacent to the second connector.

12. The display device according to claim 8 , wherein the antistatic layer is divided into a first antistatic portion and a second antistatic portion separated and insulated from each other, the first antistatic portion is adjacent to the first connector, and the second antistatic portion is electrically connected to the second connector.

13. The display device according to claim 8 , wherein a second notch is formed in the antistatic layer, and the second notch is adjacent to the first connector.

14. The display device according to claim 8 , wherein the first connector and the second connector are arranged at two ends of the binding region, respectively.

15. The display device according to claim 8 , wherein both the first connector and the second connector are made of a silver conductive adhesive.
