  • Publication number: 20230403903
    Abstract: A display panel includes: a substrate having a surface, and a plurality of pixels; and one or more light emitting elements for each pixel. The plurality of pixels are placed at different positions on the surface of the substrate. The pixels are disposed so that an occupancy rate of the light emitting elements is lower in a first region, which is part of the surface of the substrate, than in a second region, which is a region surrounding the first region and so that in the second region, the occupancy rate increases with a distance from the first region.
