<P>PROBLEM TO BE SOLVED: To provide an optical sheet suitable for a high-brightness direct backlight liquid crystal display device capable of preventing a linear light source from being seen through and improving a light-condensing function by a concave and convex lens shape part, and to provide a liquid crystal display device provided with the optical sheet. <P>SOLUTION: The optical sheet 7 is constituted by integrally laminating a resin layer 1 in which light-scattering fine particles are compounded, to a transparent resin layer 2 which has the linear concave and convex lens shape part 2a formed on the surface thereof. <P>COPYRIGHT: (C)2007,JPO&INPIT |
