Patent ID: 8648365

Claim:
A light emitting device package comprising: a package body including a cavity formed therein with first and second via holes; a first electrode extending from one side of the cavity to one side of a rear surface of the package body through the first via hole; a second electrode extending from an opposite side of the cavity to an opposite side of the rear surface of the package body through the second via hole; a light emitting device connected with the first and second electrodes; an insulating layer insulating the first and second electrodes from the package body; and a reflective layer disposed on the insulating layer having a structure in which first and second media having different refractive indexes are alternately stacked on each other, wherein the reflective layer comprises a stacked structure of an Al 2 O 3 layer and a TiO 2 layer, and wherein the light emitting device emits a light of blue wavelength, a thickness of the Al 2 O 3 layer is in a range of about 680 Å to about 730 Å, and a thickness of the TiO 2 , layer is in a range of about 480 Å to about 515 Å.
