Abstract
Provided is an organic light emitting diodes (OLED) and method of manufacturing the OLED. The OLED includes: a substrate; a light scattering layer having an uneven shape on the substrate; a transparent electrode film provided directly on and in contact with the light scattering layer; an organic light emitting layer on the transparent electrode film; and an electrode on the organic light emitting layer. The method of manufacturing the OLED includes: disposing a light scattering layer on a substrate; providing a transparent electrode film on the light scattering layer; and transferring the transparent electrode film to be directly on and in contact with the light scattering layer.
