Abstract

An organic light-emitting display and a method of manufacturing the organic light-emitting display are disclosed. In one embodiment, the organic light-emitting display includes: i) a pixel electrode disposed on a substrate, ii) an opposite electrode disposed opposite to the pixel electrode, iii) an organic emission layer disposed between the pixel electrode and the opposite electrode; a light-scattering portion disposed between the substrate and the organic emission layer, including a plurality of scattering patterns for scattering light emitted from the organic emission layer in insulating layers having different refractive indexes. The display may further include a plurality of light absorption portions disposed between the light-scattering portion and the organic emission layer to correspond to the scattering patterns.

Dependent claims

An organic light-emitting display comprising:

a pixel electrode disposed over a substrate;
an organic emission layer disposed on the pixel electrode;
an opposite electrode disposed on the organic emission layer;
a light-scattering portion disposed between the substrate and the organic emission layer, wherein the light-scattering portion comprises i) a plurality of insulating layers having different refractive indexes and ii) a plurality of scattering patterns configured to scatter light emitted from the organic emission layer, wherein the plurality of scattering patterns overlap the pixel electrode in plan view;
and
a plurality of light absorption portions separated from each other and disposed between the light-scattering portion and the organic emission layer to correspond to the scattering patterns, respectively, wherein the number of the scattering patterns is the same as that of the light absorption portions.
