Patent Images
1. A light-emitting device, comprising:
- a substrate;
a light-emitting stack above the transparent substrate and having a first diffusing surface;
a transparent adhesive layer between the substrate and the first diffusing surface; and
a first transparent conductive oxide layer above the light-emitting stack;
wherein the thickness of the first transparent conductive oxide layer is thick enough such that current is laterally spreaded substantially throughout the transparent conductive layer.

Abstract
A light emitting device having a transparent substrate, a light emitting stack, and a transparent adhesive layer is provided. The light emitting stack is disposed above the transparent substrate and comprises a diffusing surface. The transparent adhesive layer is disposed between the transparent substrate and the diffusing surface of the light emitting stack; an index of refraction of the light emitting stack is different from that of the transparent adhesive layer.
