Abstract: A light emitting device package includes a package body having a mounting region including a mounting surface for a light emitting device, a groove portion, and a bottom surface lower than the mounting surface, and a lead frame supported by the package body, a portion of the lead frame being disposed on the bottom surface and a portion of the lead frame being exposed by the groove portion. The light emitting device has a first plane on which an electrode pad is disposed, a second plane opposite the first plane, and a third plane disposed between the first plane and the second plane to connect the first plane to the second plane. The light emitting device is to be disposed in the mounting region such that the first plane is in contact with the mounting surface and the electrode pad is in the groove portion.
