1. A thin-layer LED chip comprising an epitaxial layer sequence that is disposed on a carrier element and comprises an electromagnetic-radiation-generating active region, and a reflective layer that is disposed on a principal surface of said epitaxial layer sequence facing toward said carrier element and reflects at least a portion of the electromagnetic radiation generated in said epitaxial layer sequence back thereinto, wherein-disposed on a radiation extraction surface of said epitaxial layer sequence facing away from said carrier element is a structured layer containing a glass material and exhibiting a structure that includes mutually adjacent protuberances that taper away from said radiation extraction surface and have a lateral grid size that is smaller than one wavelength of an electromagnetic radiation emitted from said epitaxial layer sequence.
