Abstract:
A display panel and a display device are disclosed and belong to the field of display technology. The display panel comprises a first substrate and a second substrate opposite to each other, a liquid crystal layer, a first electrode, and a second electrode between the first substrate and the second substrate, a waveguide layer between the first substrate and the liquid crystal layer, and a plurality of grating units which are combined with the liquid crystal layer and disposed in a same layer as the liquid crystal layer; wherein the first electrode and the second electrode are configured to adjust a refractive index of the liquid crystal layer by changing voltages applied thereto; and a coupling efficiency at which light is coupled out of the waveguide layer is determined according to a difference between a refractive index of the grating units and the refractive index of the liquid crystal layer.

Claim (Index 2):
The display panel of  claim 1 , wherein the grating unit is an echelon grating, steps in the echelon grating have different heights from each other, and the grating unit is configured to perform color separation on light of different wavelengths through a stepped structure of the echelon grating.
