Abstract: 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.

Abstract: A display device comprises a substrate including display and peripheral areas, a semiconductor element, a pixel structure, and a plurality of dummy patterns. The semiconductor element is disposed in the display area on the substrate, and the pixel structure is disposed on the semiconductor element. The dummy patterns which have stacked structure are disposed in the peripheral area on the substrate, and contain a material identical to a material constituting the semiconductor element. The dummy patterns are arranged in a grid shape in different layers, and each of the dummy patterns includes a central portion and an edge portion surrounding the central portion. The edge portions of dummy patterns which are adjacent to each other in the different layers among the dummy patterns are overlapped each other in a direction from the substrate to the pixel structure.
