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.

Abstract: A display apparatus includes pixel areas and a light blocking area between the pixel areas. The display apparatus includes a first base substrate, a thin film transistor, and first, second, and third color filters. The first color filter has a first color, the second color filter has a second color different from the first color, and the third color filter has a third color different from the first and second colors. In the light blocking area, the thin film transistor, the first color filter, and the third color filter at least partially overlap each other. The second color filter in at least one pixel area is connected to an adjacent second color filter disposed in an adjacent pixel area by a bridge portion, and the bridge portion is formed of the same material as the second color filter and is disposed in the light blocking area.
