Abstract
A display panel configured to display images is provided, each image including a plurality of image pixels and each image pixel including a plurality of sub-pixels of different colors, respectively, the display panel including: a base substrate; and a plurality of sub-beam generation components on the base substrate, each sub-beam generation component being configured to generate at least one sub-pixel in at least one image pixel of the image pixels and including: a group of light-emitting units comprising at least one light-emitting unit and corresponding to at least one sub-pixel; and a beam-expanding layer, which is arranged on a light emergent side of the group of light-emitting units and configured to expand light beams emitted from the group of light-emitting units; an orthogonal projection of the beam-expanding layer on the base substrate at least partially overlapping with an orthogonal projection of the group of light-emitting units on the base substrate.
