Abstract
The invention refers to a top-emitting device, particularly organic light-emitting diode having a layer arrangement applied on a substrate, which layer arrangement comprises a bottom electrode arranged on the substrate and a top electrode through which a light emission is effected, and also a stack of organic layers arranged between the bottom electrode and the top electrode where, at the bottom electrode, a surface facing towards the stack of organic layers is formed in light-reflecting fashion at least in a partial region and being provided with a surface structure that defines a reflection of light generated in the stack of organic layers at the bottom electrode, and where the surface structure is formed by means of mechanical shaping.
