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.
