Abstract: A display panel is provided. The display panel comprises a display panel; and a light modulation substrate disposed opposite to the display panel. The light modulation substrate includes a base layer and a transparent dielectric layer covering the base layer. The base layer has a first surface facing the display panel and an opposing second surface, and the transparent dielectric layer is disposed on the first surface of the base layer. A plurality of reflective gratings are disposed on the base layer. The transparent dielectric layer has a first surface facing the base layer and an opposing second surface, and the second surface of the transparent dielectric layer is a transparent dielectric layer surface. The transparent dielectric layer has a refractive index of n, and n>1. Outgoing light of the display device converges to a plurality of light-emitting points outside the display device.
