Abstract: A display device includes luminous and non-luminous areas. The display device includes a display element layer, an optical control layer, and a low reflective window, stacked in the order provided. The low reflective window has SCI reflectivity of 4.12% or less. The display element layer includes a pixel definition film where a pixel opening that does not overlap the luminous area is defined. A first electrode is exposed through the pixel opening. An emission layer is disposed on the first electrode. A second electrode is disposed on the emission layer. A low reflective layer is disposed on the second electrode and includes bismuth (Bi) and/or ytterbium (Yb). The optical control layer includes a color pattern part that does not overlap the luminous area, and an overcoat layer disposed on the color pattern part and overlapping the luminous and non-luminous areas.
