Abstract
A color filter substrate, a display panel and a display device are disclosed. The color filter substrate includes a base substrate, and a color filter layer and a phase inversion pattern which are disposed on the base substrate, wherein the phase inversion pattern includes a plurality of openings corresponding to a plurality of color filter units of the color filter layer, and the phase inversion pattern defines a boundary of each of the color filter units; a projection of the phase inversion pattern on the base substrate at least partially covers a projection of an area between adjacent color filter units on the base substrate; the phase inversion pattern is configured to allow light passing through the phase inversion pattern to undergo phase inversion.
