The diffuser includes nanoparticles, and guides the received first light, scatters it with the nanoparticles, and emits it as the first scattered light. The diffuser includes an incident surface to receive the first light, a first surface on which an emission surface to emit the first scattered light is formed, and a second surface opposite the first surface. The incident surface is at a first edge portion of the diffuser, the frame is opened to expose at least a portion of a region on the first surface of the diffuser in which the emission surface is formed and a region on the second surface corresponding thereto.
