Abstract:
An optoelectronic projection device which generates a predefined image during operation, including a semiconductor body having an active layer that generates electromagnetic radiation and a radiation exit side and is an imaging element of the projection device, wherein, to electrically contact the semiconductor body, a first contact layer and a second contact layer are arranged at a rear side of the semiconductor body, the rear side lying opposite the radiation exit side, and are electrically insulated from one another by a separating layer.
