Abstract
Provided are a display panel, a display device and a manufacturing method. The display panel includes a display area, the display area includes a transparent display region, where the transparent display region includes multiple transparent regions arranged in an array manner and multiple light-emitting regions disposed between adjacent transparent regions; a substrate; and multiple first light-emitting elements located on one side of the substrate and in the multiple light-emitting regions. In the transparent display region, film layers in at least two adjacent transparent regions have different thicknesses, and/or the film layers in the at least two adjacent transparent regions are made of different materials.
