Abstract

The present disclosure provides a display substrate, a display panel, a display device and a method for producing the display substrate. The display substrate includes a base substrate and a black matrix formed on the base substrate, the black matrix having physical portions and a first gap region between the physical portions, the first gap region being aligned with a clock signal line of a gate driving circuit on an opposite substrate, wherein at least one layer of first color resist is provided in the first gap region.

Claims

1. A display substrate comprising:

a base substrate and a black matrix formed on the base substrate, the black matrix having physical portions and a first gap region between the physical portions, the first gap region being aligned with a clock signal line of a gate driving circuit on an opposite substrate, wherein at least one layer of first color resist is provided in the first gap region.

2. The display substrate according to claim 1, wherein the first color resist is made from electrically insulating material.

3. The display substrate according to claim 1, wherein only one layer of first color resist is provided in the first gap region.

4. The display substrate according to claim 3, wherein the first color resist is a red color resist, a green color resist, a blue color resist, a yellow color resist, a white color resist, a cyan color resist or a black color resist.

5. The display substrate according to claim 1, wherein at least two layers of first color resist are provided in the first gap region.

6. The display substrate according to claim 5, wherein the at least two layers of first color resist comprise a layer of red color resist and a layer of green color resist stacked;

or the at least two layers of first color resist comprise a layer of red color resist and a layer of blue color resist stacked;

or the at least two layers of first color resist comprise a layer of green color resist and a layer of blue color resist stacked.

7. The display substrate according to claim 5, wherein the at least two layers of first color resist comprise a layer of red color resist, a layer of green color resist and a layer of blue color resist stacked.

8. The display substrate according to claim 1, wherein the black matrix further has a second gap region aligned with a pixel unit on the opposite substrate, a second color resist being formed in the second gap region.

9. The display substrate according to claim 8, wherein the first color resist and the second color resist which have a same color are formed by one patterning process.

10. The display substrate according to claim 1, wherein the physical portions of the black matrix are made from metal or metal oxide.

11. A display panel comprising the display substrate according to claim 1 and an opposite substrate arranged opposite to the display substrate, wherein a gate driving circuit is provided on the opposite substrate and has a clock signal line.

12. A display device comprising the display panel according to claim 11.

16. The display panel according to claim 11, wherein the first color resist is made from electrically insulating material.
