Abstract
Provided are a light emitting device and a light emitting device package comprising the same. The light emitting device comprises a first conductive type semiconductor layer, a second conductive type semiconductor layer, and an active layer. The active layer is formed between the first conductive type semiconductor layer and the second conductive type semiconductor layer. Here, at least one of the first conductive type semiconductor layer and the second conductive type semiconductor layer has current spreading structures comprising a pair of a first conductive layer and a second conductive layer and is disposed in a sequence of the second conductive layer and the first conductive layer from the active layer.
