Abstract
A display panel, a method of manufacturing the same and a display device are provided. Nano-array structures are produced on a surface of a black color resist unit of a color filter layer, so that a reflectance of the color filter layer is reduced because light is absorbed and diffuse-reflected through the nano-array structures, thereby increasing the contrast of the display panel.
