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.

Abstract: A display device is disclosed that includes a plurality of pixels and a plurality of code pixels. The pixels include light-emitting elements, which display an image. The code pixels are disposed in the same layer as the pixels and are adjacent to a reference point disposed between the pixels. The code pixels include infrared light-emitting elements, which emit infrared light. At least one of the code pixels, disposed in a particular direction from the reference point, emit the infrared light to provide a code pattern having position information.
