Abstract:
1. A light emitting device comprising: a light emitting structure having a first compound semiconductor layer, a second compound semiconductor layer and an active layer disposed between the first and second compound semiconductor layers and generating light, a portion of the first semiconductor layer being exposed; a first electrode disposed on the exposed portion of the first semiconductor layer and a second electrode disposed on a top surface of the second semiconductor layer, respectively; and a wavelength converting layer having first and second fluorescent layers sequentially formed on a first surface of the light emitting structure opposed to a second surface thereof on which the first and second electrodes formed, the first and second fluorescent layer converting a portion of the generated light to converted light having a different wavelength from the first light, wherein the first fluorescent layer has a different thicknesses from the second fluorescent layer, wherein each of the first and second fluorescent layers has a uniform thickness.
