ABSTRACT:
An enhanced light extraction OLED device including a transparent substrate; light scattering layer disposed over a first surface of the transparent substrate; a transparent first electrode layer disposed over the light scattering layer; an organic EL element disposed over the transparent first electrode layer and including one or more organic layers but at least one light emitting layer in which light is produced; and a transparent second electrode layer disposed over the organic EL element.
