Abstract

A display panel is provided with a plurality of sub-pixel areas and includes: a base substrate, a light emitting structure including a plurality of light emitting devices corresponding to the sub-pixel areas, an encapsulating layer, and a pixel defining layer. The pixel defining layer includes: a plurality of openings; at least two sub-pixel defining layers, and a quantum dot color film layer. Each of the sub-pixel defining layers is provided with a pixel separator. The pixel separators fence each of the plurality of openings, and define the plurality of sub-pixel areas. In the at least two sub-pixel defining layers, the sectional shape of the pixel separator in the sub-pixel defining layer which is farthest away from the encapsulating layer includes a regular trapezoid. The quantum dot color film layer includes a plurality of quantum dot color films arranged in the corresponding openings.
