Abstract: A display device includes subpixels on a substrate, position code patterns having a predetermined position code shape, when viewed in a plan view, each position code pattern being disposed at a region between at least two adjacent subpixels, and a pixel-defining layer defining a region where each subpixel is disposed and covering the position code patterns. The plurality of position code patterns are formed in a planar code shape and are configured to reflect light incident through the pixel-defining layer.
