Display panel and display device
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, and a liquid crystal layer, a first electrode, as second electrode, a waveguide layer and a grating layer between the first and second substrates; wherein the waveguide layer is on a side of the liquid crystal layer proximal to the first substrate; and the grating layer is in contact with the liquid crystal layer; 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 layer and the refractive index of the liquid crystal layer.
