Abstract

A display panel and a manufacturing method thereof, and a display device are provided. The display panel includes a base substrate and a plurality of pixels. Each pixel includes a plurality of sub-pixels of different colors; each sub-pixel includes a reflection layer, a first color filter layer at a side of the reflection layer away from the base substrate, a first electrode at a side of the first color filter layer away from the base substrate, a light-emitting layer at a side of the first electrode away from the base substrate, and a second electrode at a side of the light-emitting layer away from the base substrate. In each pixel, a color of the first color filter layer of the each sub-pixel is same as a color of the respective sub-pixel; thicknesses of the first color filter layers of the plurality of sub-pixels are different from each other.
