    • The lighting device disclosed in the embodiment includes a substrate, light sources disposed on the substrate at predetermined intervals, a resin layer disposed on the substrate and the light sources, and a phosphor layer disposed on the resin layer. The phosphor layer includes a first region overlapped with some of the N light sources in a direction perpendicular to the substrate and including a flat region, and a second region extending from a side surface of the first region toward the substrate and including a curved surface. The second region includes a first point horizontally in contact with the substrate from a center of a first light source closest to the side surface of the resin layer, a second point on the curved surface, and a third point where a straight line perpendicular to the substrate passes the center of the first light source, and a second distance from the center of the first light source to the second point is greater than a first distance from the center of the first light source to the first point, and is smaller than a third distance from the center of the first light source to the third point.
