Abstract: An emissive display device includes a substrate. A first electrode is disposed on the substrate. A pixel defining layer has a first opening exposing the first electrode. A second electrode is disposed on both the pixel defining layer and the first electrode. An encapsulation layer at least partially covers the second electrode. A light blocking layer is disposed on the encapsulation layer and has a second opening. A color filter is disposed on the light blocking layer. A scattering layer is disposed within the second opening of the light blocking layer and includes a plurality of scattering particles. Particle density of the scattering particles has a value of 1 ea/mm3 or more and 10 ea/mm3 or less, and a diameter of the scattering particles is 0.1 μm or more and 1.5 μm or less.

Abstract: A display device includes a display panel and an optical member. The display panel includes a lower substrate and an upper substrate. The display panel forms a light-transmitting area and a display area near the light-transmitting area. The optical member is adjacent to a rear surface of the display panel and overlaps with a portion corresponding to the light-transmitting area. The display area includes a thin film transistor and an organic light emitting element configured to receive a current from the thin film transistor. The light-transmitting area does not include a metal layer, which is disposed in the display area. The upper substrate and the lower substrate do not have a through-hole structure in the light-transmitting area.
