Abstract
A thin-film light-emitting diode chip, in which the distance between a mirror layer () and a light-generating active zone () is set in such a way that a radiation emitted by the active zone () interferes with a light reflected from the mirror layer (), the internal quantum efficiency of the active zone () being influenced by this interference and the emission characteristic of the active zone () of at least one preferred direction thereby being obtained.
