Abstract: An embodiment may comprise a lighting device comprising: a substrate comprising a first side surface to a fourth side surface; a resin layer including a plurality of grooves including a bottom surface, an exit surface, and an inclined surface; a plurality of light emitting devices disposed inside the grooves and emitting a first light; a reflective layer formed on the inclined surface; and a diffusion layer disposed on the resin layer. The plurality of grooves extends in a direction from the third side surface to the fourth side surface and are arranged in a direction from the first side surface to a second side surface. The plurality of grooves includes a first groove closest to the first side surface of the substrate and a second groove adjacent to the first groove. The first light emitted from the light emitting device disposed in the second groove is reflected off the reflective layer formed on the inclined surface of the second groove, passes through the exit surface of the second groove, is reflected off the reflective layer formed on the inclined surface of the first groove and passes through the resin layer and the diffusion layer.
