Display panel and display device
Provided a display panel and a display device, the display panel includes a first substrate, a second substrate opposite to the first substrate, a first light-shielding pattern, a second light-shielding pattern, a first electrode, a second electrode, a liquid crystal layer and a third light-shielding pattern between the two substrates in sequence; the three light-shielding patterns are configured such that light incident on the liquid crystal layer from the first substrate is prevented from exiting from the second substrate in response to an absence of voltage between the two electrodes; the two electrodes and the liquid crystal layer are configured such that the liquid crystal layer serves as an equivalent grating, and a portion of the light incident on the liquid crystal layer from the first substrate is directed to exit from the second substrate in response to the voltage between the two electrodes.
