Display panel and display device
The present disclosure provides a display panel and a display device. The display panel includes a base substrate and light-shielding strips. The base substrate includes light-shielding regions and light-transmitting regions. The display panel further includes a backlight module including a light guide plate and light extraction gratings. The display panel further includes a first electrode layer, a second electrode layer, and a liquid crystal layer. The first and second electrode layers are configured to, in response to a control signal, control the liquid crystal layer to forms a plurality of liquid crystal grating periods. The liquid crystal within each of the plurality of liquid crystal grating periods includes a plurality of segments with different refractive indices, and the refractive indices of the plurality of segments progressively increase in a direction perpendicular to an extending direction of the first electrodes in the first electrode layer.
