Abstract
A light emitting device includes a substrate including a roughened surface; a light emitter disposed on the substrate, which includes a first conductivity layer; and a mesa disposed on a partial region of the first conductivity layer. An ohmic electrode can be disposed on the mesa; and a contact electrode can be disposed on the first conductivity layer. The light emitting device further includes a first reflection layer; a first pad electrode and a second pad electrode; and a second reflection layer. The first reflection layer covers at least a portion of the light emitter, the ohmic electrode and the contact electrode. The second reflection layer is disposed on an opposite side of the substrate.
