Display device

1 . A display device having a display region, comprising:

a substrate;

a driving layer disposed on the substrate;

a self-emitting layer disposed on the driving layer and comprising a reflective electrode;

a sensor disposed in the display region; and

a spacer disposed on the self-emitting layer,

wherein the sensor does not overlap the reflective electrode in a normal direction of the substrate, and the sensor does not overlap the spacer in the normal direction of the substrate.

2 . The display device of claim 1 , further comprising a first touch electrode disposed in the display region and a second touch electrode disposed in the display region, wherein the sensor does not overlap the first touch electrode and the second touch electrode in the normal direction of the substrate.

3 . The display device of claim 2 , wherein the first touch electrode and the second touch electrode are made of metal.

4 . The display device of claim 1 , wherein the self-emitting layer is an organic light emitting diode.

5 . The display device of claim 1 , further comprising a pixel defining layer disposed on the reflective electrode and the sensor.

6 . The display device of claim 5 , wherein the pixel defining layer comprises an opening to expose the reflective electrode.

7 . The display device of claim 5 , wherein the spacer is disposed on the pixel defining layer.

8 . The display device of claim 1 , wherein the driving layer comprises a transistor, and the reflective electrode is electrically connected to the transistor.

9 . The display device of claim 8 , wherein the sensor is disposed on the substrate and adjacent to the transistor.

10 . The display device of claim 1 , wherein the sensor is disposed below the substrate.
