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: Provided are organic luminescence display and method for manufacturing the same. According to an aspect of the present invention, there is provided an organic luminescence display comprising a substrate and a plurality of pixels disposed on the substrate. The pixels comprise a plurality of first pixels, each comprising a first organic light-emitting layer, and a plurality of second pixels which are smaller than the first pixels and each of which comprises a second organic light-emitting layer. The surface roughness of the second organic light-emitting layer is greater than the surface roughness of the first organic light-emitting layer.
