  • Patent number: 10366493
    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.
