A display device includes a display layer, a plurality of touch electrodes, a light shield, and a code pattern. The display layer includes a plurality of light emission areas for emitting light. The plurality of touch electrodes are disposed on the display layer to sense a touch and surround the plurality of light emission areas. The light-shield is disposed on a portion of the plurality of touch electrodes. The code pattern is determined by a planar shape of the light-shield to have position information. The light-shield absorbs light of a specific wavelength, and another portion of the touch electrodes, which is not overlapped with the light-shield, reflects light of the specific wavelength.
