Abstract: A lighting device disclosed in an embodiment of the invention includes a substrate; a plurality of light emitting devices disposed on the substrate; a resin layer disposed on the substrate and the plurality of light emitting devices and including a lens portion; and a plurality of recess portions that seal a periphery of each of the light emitting devices and form a space spaced apart between the lens portion and the substrate. The resin layer includes a flat upper surface and a lower surface disposed on the substrate, and the lens portion may include a protrusion portion protruding toward a central portion of the light emitting device, a first incident surface having a convex curved surface around the protrusion portion, and a second incident surface extending perpendicular to the substrate from a lower portion of the first incident surface. A distance from an upper surface of the resin layer to the lower end of the protrusion portion is less than a thickness of the resin layer and is more than twice a distance from the upper surface of the resin layer to a high point of the first incident surface, and the refractive index of the recess portion is 1.2 or less.

Abstract: Disclosed herein are an illumination unit and a display apparatus. The illumination unit includes a first reflector, a second reflector arranged at either side of the first reflector, at least one light source module arranged between the first reflector and the second reflector, a cover member for covering the second reflector, an optical member arranged between the cover member and the second reflector while facing the first reflector, a first projection member interposed between the optical member and the cover member, and a second projection member interposed between the optical member and the second reflector. The distance from the cover member to one side surface of the first projection member is longer than the distance from the cover member to one side surface of the second projection member.
