The present disclosure relates to a display panel comprising a display area. The display area may include a substrate having a third opening, a thin film transistor layer on a side of the substrate, a light emitting layer on a side of the thin film transistor layer opposite from the substrate, and an encapsulation layer on a side of the light emitting layer opposite from the substrate. The thin film transistor layer may have a first opening to expose the third opening and the encapsulation layer may have a second opening to expose the third opening. Orthographic projection of the second opening on the substrate may cover orthographic projection of the third opening on the substrate.
