Claim:
1. A light emitting device package, comprising: a base including a top flat surface; an insulating layer on the base; a light emitting diode on a region of the top flat surface of the base, wherein the region is an area where the insulating layer is not disposed on the base; an optical member comprising a light transmissive material such that light emitted from the light emitting diode passes therethrough; a guiding member to guide the optical member, the guiding member having a ring shape and surrounding the region of the base; a first electrical circuit layer disposed on the insulating layer and including a first portion disposed between a top surface of the insulating layer and a first portion of a bottom surface of the guiding member; and a second electrical circuit layer disposed on the insulating layer and including a second portion disposed between the top surface of the insulation layer and a second portion of the bottom surface of the guiding member, wherein the first electrical circuit layer includes a first extension portion and a second extension portion, the first extension portion extends from the first portion of the first electrical circuit layer beyond an outside edge of the guiding member in a first direction, and the second extension portion extends from an end of the first extension portion in a second direction, wherein the second electrical circuit layer includes a third extension portion and a fourth extension portion, the third extension portion extends from the second portion of the second electrical circuit layer beyond an outside edge of the guiding member in a third direction, and the fourth extension portion extends from an end of the third extension portion in a fourth direction, and wherein the first direction and the third direction are antiparallel each other.
