Abstract: A light emitting apparatus includes a base substrate, at least a light emitting source disposed on the base substrate, and a multi-refractive layer refracting light emitted from the light emitting source, where the multi-refractive layer includes a first refractive layer and a second refractive layer disposed outside the first refractive layer, the first refractive layer having a lower index of refraction than the second refractive layer.
