    Abstract: The light source device of a display device according to the present invention has an optical waveguide, a cone sheet, and a light source disposed along the side surface of the optical waveguide. The light-emitting surface of the optical waveguide is flat, and a tilted surface that is tilted towards the light source with respect to the light-emitting surface is formed on the light-diffusing surface. The cone sheet has a flat plate and a plurality of circular cones arranged two-dimensionally on the light-incident surface of the flat plate. The central axes of the circular cones are parallel to each other. The invention provides a light source device that can be made thin and is capable of increasing the directivity of emitted light in two dimensions.

    Abstract: PROBLEM TO BE SOLVED: To provide a high-luminance and high-definition image display device capable of preventing generation of an optical defect such as a white spot while restraining deterioration of luminance performance in the image display device using a surface light source device with an edge light method. SOLUTION: The image display device includes a light guide body, a prism sheet, a primary light source, and a display panel. A light reflection surface 44 of the light guide body has a plurality of lens rows 44a. The plurality of lens rows 44a are extended substantially along a direction perpendicular to a light incident end face 41, and are arranged nearly in parallel with each other. A plurality of projected structures 45 where they are spattered are attached on the light reflection surface 44. Height projected from the light reflection surface 44 is 2 μm or more on each of the plurality of projected structures 45. On the light reflection surface 44, two or more of the other projected structures 45 are existed within a circular range having a radius of 100 times the height of the projected structure around an arbitrary projected structure 45 as the center.
