Abstract: A display apparatus including a substrate, a display portion disposed on an active area defined at the substrate, a buffer layer disposed on the active area and a pad area defined at the substrate, a touch sensing portion disposed on the buffer layer, and a pad portion disposed between the pad area and the buffer layer. The touch sensing portion includes a first pad pattern, a middle layer disposed on the first pad pattern, and a second pad pattern disposed on the middle layer. The first pad pattern is connected to the pad portion through a first contact hole defined on the pad portion in the buffer layer. The second pad pattern is connected to the first pad pattern through a second contact hole defined on the first contact hole in the middle layer.

Abstract: A display device includes a display panel includes a substrate divided into a light-emitting region and a non-light-emitting region including a sensing area, a pixel disposed on the light-emitting region, and a pixel-defining layer disposed on the non-light-emitting region, and a sensing panel which is disposed on the display panel and includes a sensing transistor configured to sense light that is emitted from the pixel and reflected by an external object. The sensing transistor overlaps the sensing area in a first direction parallel to a thickness direction of the display panel, is spaced apart from the light-emitting region in a second direction perpendicular to the first direction, and generates a current by receiving the light. The generated current may be used to sense light which is emitted from the pixel and reflected by an external object, such as a fingerprint, to allow the display to act as a biometric sensor.
