Abstract
A display panel includes a light-emitting substrate and an optical layer. The light-emitting substrate includes a light-emitting surface. The optical layer is disposed on the light-emitting surface of the light-emitting substrate and includes a prism to refract light emitted from the light-emitting substrate. The prism of the optical layer includes a bottom surface, a top surface, and a plurality of side surfaces connecting the bottom surface and the top surface. The bottom surface and the top surface are parallel to the light-emitting substrate. The bottom surface is arranged adjacent to the light-emitting substrate. The top surface is arranged away from the light-emitting substrate. An area of the top surface is smaller than an area of the bottom surface.

A display panel, comprising:
- a light-emitting substrate comprising a light-emitting surface, wherein the light-emitting substrate is an OLED display substrate;
- and
- a plurality of prisms disposed separate from each other on the light-emitting surface of the light-emitting substrate, each of the prisms being configured to refract light emitted by the light-emitting substrate;
- wherein the each of the prisms comprises a bottom surface, a top surface, and a plurality of side surfaces connecting the bottom surface and the top surface, the bottom surface and the top surface are parallel to the light-emitting substrate, the bottom surface is arranged adjacent to the light-emitting substrate, the top surface is arranged away from the light-emitting substrate, and an area of the top surface is smaller than an area of the bottom surface,
- wherein a distance between the bottom surface and the top surface ranges from 5 to 50 microns;
- wherein each of the side surfaces is composed of two sub-flat surfaces;
- wherein the two sub-flat surfaces of each of the side surfaces respectively have different normal directions, and the two adjacent sub-flat surfaces are not in parallel with the light-emitting substrate and form a recess on the corresponding side surface.
