Abstract
A display device includes a display panel including a plurality of touch electrodes, a touch driving circuit electrically connected to the plurality of touch electrodes, and a fingerprint sensor device disposed on one surface of the display panel and including a plurality of unit blocks. The fingerprint sensor device includes a plurality of fingerprint scan lines extending in a first direction, a plurality of fingerprint sensing lines extending in a second direction crossing the first direction, a plurality of sensor pixels respectively connected to the plurality of fingerprint scan lines and the plurality of fingerprint sensing lines, and a fingerprint scan driver having a plurality of stages for applying a fingerprint scan signal to each of the plurality of fingerprint scan lines. The touch driving circuit applies a start signal to the fingerprint scan driver.
