    • A direct type backlight unit 1 comprising a light source 13, a diffusing plate 14 disposed over the light source, and an optical member 15 disposed on the diffusing plate, or an edge light type backlight unit comprising a light conducting plate and an optical member disposed on the light conducting plate, wherein the surface of the optical member 15 contacting with the diffusing plate or the light conducting plate (henceforth referred to as optical element) is formed from a material containing a thermosetting resin and/or a thermoplastic resin, and polyethylene type wax particles having a mean particle diameter of 4 to 10 μm. The content of the polyethylene type wax particles is 0.20 to 0.50 part by weight based on 100 parts by weight of resin component of the resin layer. Even when a molded article comprising an amorphous olefin resin or a polycarbonate resin is used as the optical element, adhesion of the optical element and the optical member 15 contacting with it can be prevented, and generation of scratches on the optical element as the molded article by the optical member 15 can be reduced.
