Abstract: A light emitting device package includes a reflective unit having a first surface and a second surface opposing the first surface and having a through hole formed in a central portion of the reflective unit to penetrate through the first and second surfaces, a light emitting device disposed in the through hole and externally exposed to one of the first and second surfaces, and an optical device disposed on the first surface of the reflective unit to cover the light emitting device. The optical device allows light generated by the light emitting device to be partially transmitted and partially reflected to be emitted externally.
