Abstract:
1. A light emitting device, comprising: a substrate; a reflection electrode disposed on the substrate, the reflection electrode including a first groove; a light transmitting electrode disposed on the reflection electrode, the light transmitting electrode including a second groove corresponding to the first groove; a current blocking layer disposed in the second groove; a light emitting structure disposed on the light transmitting electrode and the current blocking layer, the light emitting structure comprising a first semiconductor layer, a second semiconductor layer, and an active layer interposed between the first and second semiconductor layer; and an electrode disposed on the light emitting structure and vertically overlapping at least a portion of the current blocking layer, wherein the light transmitting electrode has a thickness of 20 to 200 Å, and wherein the light transmitting electrode has bent portions respectively extending in parallel with two opposite lateral side surfaces of the reflection electrode, the bent portions of the light transmitting electrode each being spaced apart from the respective lateral side surface of the reflection electrode, and wherein the light transmitting electrode is arranged such that it is in partial contact with both of the two opposite lateral side surfaces of the reflection electrode.
