Abstract
A light emitting device includes at least one light emitting unit that includes an insulating layer, a first electrically conductive layer, and a semiconductor layer structure having at least one recess. The first electrically conductive layer and the insulating layer extend into the recess. A contact area between a conductive protrusion portion of the first electrically conductive layer and a first-type semiconductor layer of the semiconductor layer structure is larger than 1.5% of an area of a bottom surface of the first-type semiconductor layer. A method for producing the light emitting device is also disclosed.
