Abstract:
1. A light-emitting device comprising: a conductive substrate; a light-emitting structure layer configured above the conductive substrate; a metallic reflective layer configured between the light-emitting structure layer and the conductive substrate; a transparent conductive layer configured between the light-emitting structure layer and the metallic reflective layer; a first patterned dielectric layer configured between the light-emitting structure layer and the transparent conductive layer, the first patterned dielectric layer comprising a plurality of first structure units, the first structure units being separated from one another by a first space, wherein first portions of the transparent conductive layer are located in the first spaces respectively; and a second patterned dielectric layer configured between the transparent conductive layer and the metallic reflective layer, the second patterned dielectric layer comprising a plurality of second structure units, the second structure units being separated from one another by a second space, wherein second portions of the transparent conductive layer are located in the second spaces respectively, and the first portions and the second portions are not overlapped.
