Abstract
A display panel and a manufacturing method thereof, and a display device are disclosed. The display panel includes: a substrate, a plurality of pixel units and a pixel defining layer, each of at least one of the pixel units comprises an organic functional layer, and the organic functional layer has a raised edge; an orthographic projection of the organic functional layer of each pixel unit on the substrate is surrounded by an orthographic projection of the second defining layer on the substrate, an orthographic projection of the first defining layer on the substrate covers the orthographic projection of the second defining layer on the substrate, and the orthographic projection of the first defining layer on the substrate overlaps with an orthographic projection of at least a portion of the raised edge on the substrate the brightness uniformity of the display panel may be improved.
