As illustrated by FIGS. 1A to 2B, the display panel includes a display substrate 10, an optical adhesive layer 20, and a cover plate 30. The cover plate 30 is located on a side of the optical adhesive layer 20 away from the display substrate 10, and is connected to the display substrate 10 through the optical adhesive layer 20.
The display substrate 10 includes a flexible base substrate 11 (not labeled in FIG. 1A), and includes a plurality of light emitting elements 12 (as illustrated by FIG. 1G), a pixel defining layer PDL, and an encapsulation layer EPL, the plurality of light emitting elements 12, the pixel defining layer PDL, and the encapsulation layer EPL are disposed on the base substrate 11. The pixel defining layer PDL is used to separate the plurality of light emitting elements 12 (as illustrated by FIG. 1G), that is, the pixel defining layer PDL is used to define a plurality of sub-pixel regions, each of which is provided with one light emitting element 12.
