Abstract
Provided is a display device including an illuminance sensor. The illuminance sensor includes a read-out line disposed on a substrate and extending in a first direction, a light receiving element disposed on the read-out line, a first sensor transistor configured to control a sensing current based on a voltage of a sensor node, which is a first electrode of the light receiving element, a second sensor transistor configured to supply a reset voltage to the sensor node based on a reset signal, a third sensor transistor configured to electrically connect a first electrode of the first sensor transistor to the read-out line based on a gate signal, and a sensor capacitor comprising a first capacitor electrode electrically connected to the first electrode of the first sensor transistor, and a second capacitor electrode overlapping the first capacitor electrode and electrically connected to the first electrode of the light receiving element.
