Abstract

A color filter substrate, a display panel and a display device are provided. The color filter substrate includes: a base substrate; a color conversion layer on the base substrate; a covering layer on a side of the color conversion layer away from the base substrate; and a polarizing layer on a side of the covering layer away from the base substrate. The polarizing layer includes a wire grid polarizer. The covering layer includes a first covering sub-layer and a second covering sub-layer, the first covering sub-layer is located on the side of the color conversion layer away from the base substrate, the second covering sub-layer is located on a side of the first covering sub-layer away from the base substrate, and a material of the first covering sub-layer is different from a material of the second covering sub-layer.
