1. A display device comprising:
an organic light emitting device layer;
a thin film encapsulation layer on the organic light emitting device layer, the thin film encapsulation layer having a first surface adjacent to the organic light emitting device layer and a second surface opposite the first surface and spaced from the organic light emitting device layer;
a buffer layer directly on the second surface of the thin film encapsulation layer; and
a touch sensing unit directly on the buffer layer, the touch sensing unit comprising:
a first conductive pattern on the buffer layer;
an insulating layer covering the first conductive pattern; and
a second conductive pattern on the insulating layer and electrically insulated from the first conductive pattern, the second conductive pattern having a thickness above the first conductive pattern in a thickness direction of the display device that is greater than a thickness of the first conductive pattern in the thickness direction of the display device.
