<P>PROBLEM TO BE SOLVED: To provide a light guide in which high luminance can be accomplished by improving the surface light emitting efficiency of the guide itself to the maximum level so that the light guide is made suitable for display devices used in office automation apparatuses such as personal computers, word processors, etc. and various monitors displaying image signals such as panel monitors, television monitors, etc., display devices used in illuminators for indoor or outdoor space, and signs. <P>SOLUTION: The light guide, which is made of a transparent thermoplastic resin composition and is used for a large liquid crystal display device that is equal to or greater than fifteen inches, contains a transparent thermoplastic resin and aluminum trioxide fine particles. The refractive index and the average particle diameter of the aluminum trioxide fine particles are 1.7 to 1.8 and 0.01 to 1.0 μm, respectively and the amount of the aluminum trioxide fine particles with respect to the weight of the transparent thermoplastic resin is 1 to 7 ppm. <P>COPYRIGHT: (C)2007,JPO&INPIT |
