2 . The color filter substrate according to claim 1 , wherein the black matrix is made of metal or alloy.

3 . The color filter substrate according to claim 2 , wherein the black matrix is made of one of chromium, chromium alloy, copper, and aluminum.

4 . The color filter substrate according to claim 1 , wherein the color filter layer comprises red regions, green regions and blue regions, wherein the color filter layer is configured so that any two adjacent regions of the red regions, the green regions and the blue regions are regions with different colors and have margins overlapped with each other.

5 . The color filter substrate according to claim 3 , wherein the color filter layer comprises red regions, green regions and blue regions, wherein the color filter layer is configured so that any two adjacent regions of the red regions, the green regions and the blue regions are regions with different colors and have margins overlapped with each other.

6 . The color filter substrate according to claim 1 , further comprising a transparent protective layer disposed on a surface of the color filter layer away from the substrate, for protecting the black matrix and the color filter layer.

7 . The color filter substrate according to claim 5 , further comprising a transparent protective layer disposed on a surface of the color filter layer away from the substrate, for protecting the black matrix and the color filter layer.

8 . The color filter substrate according to claim 6 , further comprising spacers disposed on a surface of the transparent protective layer away from the substrate, for maintaining a thickness of a liquid crystal cell assembled by the color filter substrate and an array substrate.

9 . The color filter substrate according to claim 8 , wherein the spacers comprise main spacers and secondary spacers, wherein the main spacers have a greater height than the secondary spacers.

10 . The color filter substrate according to claim 7 , further comprising spacers disposed on a surface of the transparent protective layer away from the substrate, for maintaining a thickness of a liquid crystal cell assembled by the color filter substrate and an array substrate.

11 . A display device comprising the color filter substrate according to claim 1 .
