An RGB light emitting diode package with improved color mixing properties includes red, green, and blue light emitting diode chips provided on a reflector. A photomixing material and a filler resin scatters rays so as to uniformly mix the rays emitted from the light emitting diode chips. The photomixing material and filler resin are applied onto upper sides of the light emitting diode chips while being mixed with each other, and the photomixing material is uniformly dispersed in the filler resin.
