Abstract
Provided is a display panel, including: a base substrate, a light emitting device layer provided on the base substrate and including light emitting devices, and a light adjustment structure layer provided at a side of the light emitting device layer facing away from the base substrate and including light adjustment units and a dielectric layer covering the light adjustment units. Each light adjustment unit has a smaller refractive index than the dielectric layer and includes a light adjustment sub-section and a through hole penetrating the light adjustment unit in a direction perpendicular to the base substrate. The through hole overlaps one light emitting device, and the light adjustment sub-section surrounds the through hole. For one light adjustment unit, a thickness of the light adjustment sub-section gradually increases in a direction from the through hole to the light adjustment sub-section.
