Abstract
An optoelectronic device, in particular a display device, comprises: at least one optoelectronic light source, an at least partially transparent front layer, an at least partially transparent support layer, wherein the light source is arranged between the front layer and the support layer, wherein a front side of the light source faces the front layer and a rear side of the light source faces the support layer, and wherein a limiting device is provided in a circumferential direction around the light source, wherein the limiting device limits a spatial region, in which the light source emits light such that total internal reflection of the emitted light, in particular at an interface between the front layer and the outside, is avoided or at least reduced.
