Abstract: A display device includes a display panel and a diffraction pattern layer. The display panel includes pixels. The diffraction pattern layer includes diffraction patterns arranged on the display panel and configured to diffract at least a portion of light from the pixels. The pixels include a first unit pixel and a second unit pixel. The diffraction patterns include first unit diffraction patterns and second unit diffraction patterns. The first unit diffraction patterns are arranged on the first unit pixel. The second unit diffraction patterns are arranged on the second unit pixel. The second unit diffraction patterns have a different planar arrangement than the first unit diffraction patterns.
