Abstract
A display device includes: a display panel including a pixel array layer on one surface of a first substrate for displaying an image; a sound generator for transmitting an ultrasound; and an ultrasonic sensor for receiving an ultrasound reflected by an object on the display panel. The sound generator and the ultrasonic sensor are on the other surface of the first substrate opposite to the one surface of the first substrate. The ultrasonic sensor includes a plurality of ultrasonic sensor units arranged in a matrix form, and the ultrasonic sensor senses the object using the reflected ultrasound received by the plurality of ultrasonic sensor units.
