Abstract

A light-emitting device is disclosed comprising an organic light-emitting diode structure and an encapsulation comprising a light-transmitting window with at least a first inorganic layer, an organic layer and a second inorganic layer, the organic layer comprising domains of a dispersed first organic component embedded by a second component, the first and the second component having a mutually different refractive index, the organic layer being sandwiched between the first and the second inorganic layer.
