Abstract:
A light emitting device including a light emitting structure having a first conductive semiconductor layer, an active layer disposed under the active layer and a second conductive semiconductor layer disposed under the active layer; a trench formed in a portion of the light emitting structure; a current barrier layer in the trench and configured to hinder current supply to the active layer at a portion where the trench is located and to block the active layer over the trench from emitting light; and a first electrode on the first conductive semiconductor layer above the portion where the trench is located.
