Abstract
A display panel includes a substrate, and a pixel defining layer and a cathode layer that are laminated on the substrate. The pixel defining layer includes a plurality of strip-shaped first pixel defining structures and a plurality of strip-shaped second pixel defining structures. A slope angle of the second pixel defining structure is greater than a slope angle of the first pixel defining structure, and the second pixel defining structure is configured to separate portions of the cathode layer on two sides of the second pixel defining structure.
