Abstract
A display device may include: a first touch sensor including first sensing electrodes and second sensing electrodes, arranged in a sensing area intersecting each other; a display panel including: pixels arranged in a display area overlapping with the sensing area; and a second touch sensor including photo sensors disposed between the pixels or in the pixels; and a driving circuit configured to drive the first touch sensor and the display panel, wherein the driving circuit may be configured to detect a touch input by comparing a first touch detection value detected by the first touch sensor and a second touch detection value detected by the photo sensors.
