Claim:
1. A light emitting device package, comprising: a substrate; a light emitting structure provided under the substrate, the light emitting structure including a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer; a first electrode configured to penetrate the second conductive semiconductor layer and the active layer to contact the first conductive semiconductor layer; a contact layer configured to contact the second conductive semiconductor layer; a first insulation layer disposed between the second conductive semiconductor layer and the first electrode and between the active layer and the first electrode, the first insulation layer covering a side portion and an upper portion of the contact layer; and a second electrode configured to penetrate the first insulation layer to contact the contact layer, wherein the first insulation layer includes at least two layers, which are repeatedly formed to form a multilayer structure, and wherein the at least two layers are formed of materials having different coefficients of thermal expansion.
