The second substrate has a light-shielding region shielded by the light-shielding pattern and light-exiting regions not shielded by the light-shielding pattern. A pixel electrode in the pixel electrodes is configured to converge light entering the pixel electrode from the first substrate; and the pixel electrode is used to control a deflection state of a liquid crystal in the liquid crystal layer, so that light passing through the pixel electrode is incident to the light-shielding pattern and/or a corresponding light-exiting region.
