Abstract: The present disclosure discloses a display panel, a method for manufacturing a display panel, and a display device, and belongs to the field of liquid crystal display technologies. The display panel includes an array substrate, a counter substrate, and a liquid crystal layer between the array substrate and the counter substrate. For the array substrate, a diffuse reflection layer is sequentially laminated on the array substrate. The array substrate includes a first base substrate, and a thin film transistor array, a diffuse reflection layer, and a first planarization layer that are laminated on the first base substrate. A surface of the diffuse reflection layer proximal to the first planarization layer is a reflection surface that has a plurality of protrusion structures, the protrusion structures are configured to diffusely reflect light irradiated on the reflection surface. Based on this structure, the first planarization layer may separate the protrusion structure from the liquid crystal layer to prevent the protrusion structure from affecting the driving effect of the liquid crystal layer. In this way, the problem in the related art regarding the poor display effect of the display panel is solved and thus the display effect of the display panel is improved.
