Abstract
A display device includes a pixel including a display driver configured to apply a driving current to a light-emitting element; and an optical sensor including a sensing driver configured to apply a sensing current to a read-out line based on a photocurrent from the photoelectric conversion element, wherein the pixel further includes, a driving transistor configured to control the driving current, a first transistor configured to apply a first initialization voltage to an anode of the light-emitting element based on an emission control signal, and a second transistor configured to connect the anode of the light-emitting element to a first electrode of the driving transistor in accordance with the emission control signal, and wherein a channel of the first transistor is a different material from channels of the driving transistor and the second transistor.
