A display panel including a plurality of pixel units is provided. The display panel includes: a first substrate and a second substrate opposite to each other a first light-shielding layer including a plurality of first openings as light-transmitting regions for the pixel units, and a liquid crystal layer between the first substrate and the second substrate. Each pixel unit includes a first electrode, a second electrode and a lens. The first electrode and the second electrode are configured to form an electric field in response to receiving a voltage, the electric field is configured to drive liquid crystal molecules of the liquid crystal layer to deflect to change a ratio of transmission and reflection of linearly polarized light incident onto the liquid crystal layer at the light incident surface of the lens.
