Color filter substrate, display panel and display device

Abstract

The disclosure discloses a color filter substrate, a display panel and a display device. The display panel includes a plurality of pixels, each of which includes a plurality of sub-pixels of various colors. The color filter substrate includes a base substrate, a plurality of black matrixes formed on the base substrate, a plurality of opening regions disposed between the back matrixes and corresponding to the sub-pixels in a one-to-one correspondence relationship, and a color filter layer filled in each of the opening regions; the color filter layer is doped with quantum dots which can generate light after excited, color of which is the same as the color of the corresponding sub-pixels. The color filter substrate improves purity of light transmitted through the color filter layer and in turn improves display color gamut of the display device.
