Abstract
An LED chip includes a carrier, a semiconductor layer sequence, a reflective layer sequence arranged in regions between the carrier and the semiconductor layer sequence, wherein the reflective layer sequence includes a dielectric layer facing the semiconductor layer sequence and a metallic mirror layer facing away from the semiconductor layer sequence, and an encapsulating layer arranged in places between the carrier and the reflective layer sequence, the encapsulating layer extending in places through the reflective layer sequence into the semiconductor layer sequence and thus forming a separating web separating an inner region of the reflective layer sequence from an edge region of the reflective layer sequence.
