ORGANIC LIGHT EMITTING DEVICE

摘要

An organic light emitting device comprises a substrate, a first electrode (22) layer, a second electrode (23) and an organic layer comprising electroluminescent material (21) sandwiched between the two electrodes and supported by a substrate (24). The first electrode and the substrate are transparent for radiation emitted by the light emitting layer (21). According to the invention, the organic layer (21) and the first electrode layer (22) are wave shaped. By this, waveguiding effects in the transparent layers may be reduced, and the out-coupling efficiency may be enhanced.
