Abstract

The display panel, the preparation method of the display panel and the display device provided by the embodiments of the present application comprise: an operable area, an edge pixel area and a non-display area, the edge pixel area is between the non-display area and the operable area; the color filter layer in the edge pixel area is parallel to the direction of the display panel, and the thickness of the color filter layer in the edge pixel area is the same as that of the color filter layer in the operable area, and the height of the color filter layer in the edge pixel area is flush with that of the color filter layer in the operable area, which can solve the problem of abnormal brightening of the screen around the display panel caused by the uneven film thickness of the color filter layer to a certain extent, and the display panel has good display effect.
