Abstract

A display panel includes a plurality of sub-pixels. At least one sub-pixel of the plurality of sub-pixels includes a first electrode, a light modulation structure disposed on a side of the first electrode, and a second electrode disposed at a side of the light modulation structure away from the first electrode. The light modulation structure includes a refractive index adjustment layer, and a light modulation layer disposed between the refractive index adjustment layer and the first electrode. A refractive index of the refractive index adjustment layer is changed under action of an electric field between the first electrode and the second electrode. The light modulation layer is in contact with the refractive index adjustment layer, and at least a part of a surface of the light modulation layer that is in contact with the refractive index adjustment layer is a curved face.
