    Abstract: A display panel includes a base layer, a circuit layer, and a pixel layer. The base layer includes a plurality of light emitting areas, and a plurality of transmitting areas to transmit light incident thereto. The circuit layer includes a plurality of switching devices disposed on the light emitting areas, and a plurality of photosensors disposed on the transmitting areas. The pixel layer includes a light emitting element to emit light based on reception of a current from at least one of the plurality of switching devices. The light emitting element overlaps with one of the plurality of light emitting areas. At least one of the plurality of photosensors is configured to receive a portion of external light reflected from an external object after transmission of the external light through at least one of the plurality of transmitting areas.

    Abstract: A display apparatus includes a substrate, a display area including a plurality of pixels, a non-display area outside the display area, a first dam surrounding the display area, a second dam surrounding the first dam, a third dam between the display area and the first dam. The third dam including a first insulating layer and a second insulating layer on the first insulating layer, and a thin film encapsulation layer covering the display area, the thin film encapsulation layer including at least one inorganic encapsulation layer and at least one organic encapsulation layer. The third dam includes a first region in which the second insulating layer is spaced along a direction in which the first insulating layer extends, and a second region in which the second insulating layer is continuously present along the direction in which the first insulating layer extends, the second region not overlapping the first region.
