Abstract
A light emitting device includes a stack of layers of a substrate, with a basic layer, first and second electrode layers, and an organic light-emitting layer which is sandwiched between the first and the second electrode layers. At least a part of the basic layer is covered by a shielding structure that includes a plurality of lamella elements that extend sheet-like from the stack of layers in such a way, that the lamella elements guide light out of the light emitting device.
