Light emitting device

Abstract

Provided is a light emitting device, including a substrate; a first light emitting chip for emitting first color light, the first light emitting chip being disposed on the substrate, the first light emitting chip including a first substrate and a first light emitting layer, the first substrate including first surface and second surface opposite to the first surface, the first light emitting layer being positioned on the first surface; a second light emitting chip for emitting second color light different from the first color light, the second light emitting chip being disposed on the first light emitting chip, the second light emitting chip including a second substrate and a second light emitting layer, the second substrate including third surface and fourth surface opposite to the third surface, the second light emitting layer being positioned on the third surface; the second surface being opposite to the fourth surface.

Dependencies are inferred from the claim text.
