1. A light-emitting device, comprising:
- an epitaxial structure comprising an active layer;
a transparent substrate having a top surface being not less than 1.6 times an area of the active layer;
a first transparent layer, directly connected to the transparent substrate and comprising a widest width smaller than that of the transparent substrate and larger than that of the epitaxial structure;
a second transparent layer, made of oxygen and only one metallic element, arranged between the first transparent layer and the epitaxial structure; and
a first electrode arranged on the first transparent layer and the second transparent layer which are not covered by the active layer,wherein the second transparent layer and the transparent substrate have outmost sidewalls which are not coplanar with each other.

Abstract
A light-emitting device includes a transparent substrate, a transparent adhesive layer on the transparent substrate, a first transparent conductive layer on the transparent adhesive layer, a multi-layer epitaxial structure and a first electrode on the transparent conductive layer, and a second electrode on the multi-layer epitaxial structure. The multi-layer epitaxial structure includes a light-emitting layer. The transparent substrate has a first surface facing the transparent adhesive layer and a second surface opposite to the first surface, wherein the area of the second surface is larger than that of the light-emitting layer, and the area ratio thereof is not less than 1.6.
