Title: OPTOELECTRONIC DEVICE
Abstract:
The invention relates to an optoelectronic device (10) which comprises a substrate (11), a functional layer structure (16) that is designed to generate electromagnetic radiation when supplied with power by a first electrode (14) and a second electrode (15), and a planarized portion (12) for leveling out a roughness of a main face (11a) of the substrate (11) facing the electrodes (14). The optoelectronic device is characterized in that the planarized portion (12) is designed and disposed such that an interface (14a, 15b) of one of the electrodes (14, 15) has a lower roughness in at least one first region (34a, 35a) than in a second region (34b, 35b).
