LIGHT EMITTING ELEMENT AND METHOD FOR PRODUCING LIGHT EMITTING ELEMENT

摘要

The present invention provides a light emitting element which comprises a supporting substrate that also serves as a window layer and a light emitting part that is provided on the window layer/supporting substrate and sequentially comprises a second semiconductor layer of a second conductivity type, an active layer and a first semiconductor layer of a first conductivity type in this order. This light emitting element is characterized in that: a first ohmic electrode is provided on the first semiconductor layer with a first selective etching layer being interposed therebetween; the surface of the first semiconductor layer and at least a part of the lateral surface of the light emitting part are covered by an insulating protective film; and the surface of the first semiconductor layer and the surface of the window layer/supporting substrate are subjected to surface roughening. Consequently, the present invention provides a light emitting element which comprises a window layer/supporting substrate and a light emitting part and performs element isolation, while being suppressed in electrode separation from the surface of the light emitting part and having improved luminous efficiency.
