Disclosed is a light emitting device including a substrate, a light emitting structure arranged on the substrate, the light emitting structure including a first semiconductor layer, a second semiconductor layer and an active layer arranged between the first semiconductor layer and the second semiconductor layer, a first electrode electrically connected to the first semiconductor layer, and a second electrode electrically connected to the second semiconductor layer, wherein the light emitting structure has a top surface including a first side and a second side which face each other, and a third side and a fourth side which face each other.

Light emitting device

Disclosed is a light emitting structure comprising a first semiconductor layer, a second semiconductor layer, and an active layer disposed on between the first and second semiconductor layers, a first electrode electrically connected to the first semiconductor layer and a second electrode electrically connected to the second semiconductor layer. The first semiconductor layer is formed, at an edge portion thereof, with a hole, in which a portion of the first electrode is arranged.

A light-emitting device includes a substrate, a light-emitting structure on the substrate, the light-emitting structure including a first semiconductor layer, an active layer and a second semiconductor layer, a light-transmitting electrode layer on the second semiconductor layer, and a first reflective layer on the light-transmitting electrode layer, wherein the first reflective layer includes a first layer having a first index of refraction and a second layer having a second index of refraction different from the first index of refraction. Based on this configuration, it is possible to protect the light-emitting device and improve luminous efficiency thereof.
