Abstract

A display panel includes a substrate; an array layer, disposed on the substrate; a light-emitting structure layer, disposed on the side of the array layer away from the substrate and including a plurality of sub-pixels, including first and second sub-pixels of a same color. The display panel includes first adjustment units and second adjustment units, disposed on the light-emitting structure layer. The first adjustment units are in one-to-one correspondence with the first sub-pixels, and vertical projections of each first adjustment unit and the corresponding first sub-pixel at least partially overlap. The second adjustment units are in one-to-one correspondence with the second sub-pixels, and vertical projections of each second adjustment unit and the corresponding second sub-pixel at least partially overlap. Light beams with a same phase, after passing through a first adjustment unit and a second adjustment unit, have a non-zero phase difference.
