There is provided a white light emitting device including a light emitting chip, which can emit a first light having a wavelength between 340 nm and 495 nm; an organic phosphor layer, which is formed by applying an organic polymer on the output surface of the light emitting chip using coating, screen printing, offset printing, sputtering, dripping, casting, adhering, or vacuum evaporation method; and an encapsulation layer embedded with a plurality of nanograde crystalline grains, which encloses the light emitting chip and the organic phosphor layer, wherein the first light emitted from the light emitting chip can excite the organic phosphor layer, which subsequently emits a second light having a wavelength between 530 nm and 580 nm, and the second light and the first light are mixed within the encapsulation layer to produce a white light with excellent color uniformity and color rendering outwards from the encapsulation layer.
