Abstract
A display panel includes a first substrate, a second substrate disposed opposing the first substrate, a first transparent layer, a first light shield layer, and a photosensitive element layer located between the first substrate and the second substrate. The first transparent layer, the first light shield layer, and the photosensitive element layer are sequentially disposed along a direction from the first substrate to the second substrate. The first transparent layer includes a plurality of protrusions extending toward the first substrate. The first light shield layer includes a plurality of first openings, and the photosensitive element layer includes a plurality of photosensitive elements for acquiring a fingerprint image. The protrusions, the first openings, and the photosensitive elements have one-to-one correspondence, and have at least partially overlapped orthographic projections on the second substrate.
