Abstract: According to an aspect of the present disclosure, a display device includes a substrate including a display area and a non-display area, an organic light emitting diode disposed on the substrate, an encapsulation layer disposed on the organic light emitting diode, a touch sensing unit disposed on the encapsulation layer in the display area, a plurality of touch pads disposed in the non-display area, a plurality of touch link lines disposed in the non-display area and each electrically connecting the touch sensing unit and any one of the plurality of touch pads, and an electrostatic discharge circuit disposed in the non-display area and connected to the plurality of touch link lines. In this case, since the electrostatic discharge circuit is connected to the plurality of touch link lines, static electricity accumulated in the touch sensing unit is easily discharged to the outside, thereby suppressing electrostatic defects.
