Light emitting device and light emitting device package thereof

A light emitting device package comprising:

• a package body;
• a light emitting device on the package body;
• a first electrode layer and a second electrode layer provided on the package body connected to the light emitting device;
• and
• a resin layer which surrounds the light emitting device,
• wherein the light emitting device includes;
• a light emitting structure including a second conduction type semiconductor layer, an active layer, and a first conduction type semiconductor layer;
• a second electrode layer arranged under the light emitting structure;
• a first electrode layer having at least portion extending to contact the first conduction type semiconductor layer passing the second conduction type semiconductor layer and the active layer;
• and
• an insulating layer arranged between the second electrode layer and the first electrode layer, between the second conduction type semiconductor layer and the first electrode layer, and between the active layer and the first electrode layer,
• wherein said at least one portion of the first electrode layer contacting the first conduction type semiconductor layer has a roughness.
