1. A light emitting device package, comprising:
a body including a cavity; first and second lead electrodes disposed in the cavity of the body; a light emitting device disposed in the cavity, electrically connected to at least one of the first and second lead electrodes and emitting a first main peak wavelength in the range of 410˜460 nm; a first resin layer having first phosphor on the light emitting device; a second phosphor emitting light of a third main peak in the cavity; and a second resin layer on the first resin layer, and the first phosphor in the second resin layer, wherein the first phosphor of the first resin layer emits light of a second main peak wavelength in the range of 461 nm˜480 nm by exciting some light having the first main peak wavelength, and the first and second main peak wavelengths have the wavelength different from each other and contain light having a same color, wherein the light emitting device is a blue LED chip, wherein the first phosphor is a blue phosphor, wherein the first phosphor emits a blue light having a wavelength difference of 5 nm to 69 nm from the first main peak wavelength, and wherein the second phosphor emits the light of the third main peak longer than the second main peak.
