摘要： A display device includes a display part including multiple unit pixels, each of the unit pixels including multiple display pixels and a light sensing pixel, multiple touch electrodes disposed between the display pixels and the light sensing pixel, surrounding circumferences of the display pixels and the light sensing pixel, and sensing a touch, and a main driving circuit sensing a fingerprint by the light sensing pixel. The light sensing pixel in one of the unit pixels and the light sensing pixel in another one of the unit pixels have different light transmissivities for external light, and the main driving circuit analyzes light sensing signals of the light sensing pixels having the different light transmissivities to detect a luminance value or an illuminance value of the external light.
