Abstract: A display device includes: a display layer and a sensor layer, which senses an external input. The display layer includes: a plurality of pixels and a plurality of sensors, each of which includes a sensing element and a sensor driving circuit connected to the sensing element. The sensor driving circuit includes: a reset transistor, an output transistor, and a switch transistor including a first electrode connected to the sub-readout line, a second electrode connected to a readout line, and a third electrode for receiving a switch signal generated based on the external input.
