A light-emitting diode includes a transparent substrate with a first surface, a second surface opposite to the first surface, and a side surface connected to the first surface and the second surface; a first light-emitting structure; a second light-emitting structure; a connecting layer, connected to the first light-emitting structure and the second light-emitting structure; a circuit arranged between the transparent substrate and the first light-emitting structure, and having a portion formed on the first surface without extending to the second surface; and a structure with diffusers, covering the first light-emitting structure and the second light-emitting structure on the first surface without crossing over the side surface.
