Abstract
An optoelectronic semiconductor chip and a method for producing an optoelectronic semiconductor chip are disclosed. In an embodiment an optoelectronic semiconductor chip includes a semiconductor layer sequence having a plurality of pixels, the semiconductor layer sequence comprising an active layer configured to generate electromagnetic radiation of a first wavelength range and a plurality of conversion elements, wherein each conversion element is configured to convert the radiation of the first wavelength range into radiation of a second wavelength range, wherein each pixel has a radiation exit surface and a conversion element is arranged on each radiation exit surface, and wherein each conversion element has a greater thickness in a central region than in a peripheral region.
