Disclosed is a light-emitting device package including; a body having a cavity formed therein, a light source mounted in the cavity, a resin layer which fills the cavity and is transmissive, and at least one optical sheet provided on the resin layer, wherein the optical sheet includes a first layer, and a second layer which is provided on the first layer and has a plurality of linear prisms, wherein the first layer has a first refractive index and the resin layer has a second refractive index, and wherein the first refractive index is equal to or greater than the second refractive index. Accordingly, the light-emitting device package may have improved luminous efficacy, enable uniform distribution of emitted light, and prevent degradation of a phosphor.
