Claim:
1. A light emitting device comprising: a light emitting chip which generates a first light having a first color; a first cavity layer disposed on the light emitting chip and having a first refractive index, wherein the first cavity layer generates a second light having a second color different from the first color; a second cavity layer disposed on the first cavity layer and having a second refractive index different from the first refractive index, wherein the second cavity layer generates a third light having a third color different from the first color and the second color; a first half mirror layer disposed between the first cavity layer and the light emitting chip, wherein the first half mirror layer reflects at least a portion of the second light; a second half mirror layer disposed between the first cavity layer and the second cavity layer, wherein the second half mirror layer reflects at least a portion of the third light; and a third half mirror layer disposed on the second cavity layer, wherein the third half mirror layer transmits the first light, wherein the first cavity layer resonates the second light, and the second cavity layer resonates the third light.
