Abstract: A display device includes a display panel including a pixel and a sensor pixel, the pixel including a light emitting element and a driving transistor controlling a current flowing through the light emitting element, the sensor pixel including sensor transistors, a data driver that supplies a data signal to the pixel through a data line and provides a sensor data signal to the sensor pixel through a sensor data line, and a sensing driver that obtains sensing information on a current flowing through the sensor pixel. The sensor transistors are electrically connected in parallel to each other and are commonly electrically connected to the sensor data line. The sensor transistors and the driving transistor include a substantially same characteristic.
