<P>PROBLEM TO BE SOLVED: To enable to make a light-emitting face with uniform brightness without luminance unevenness, when light is guided to a light guide plate as a backlight or a lighting system, and solve the problem of a light control pattern that is visible of the light guide plate. <P>SOLUTION: The light guide plate has one face as a reflecting face 12, another face facing the reflective face as a light-emitting face 11, and at least a side face a light-incident face 13 for guiding in light. A light control pattern 14 is formed on the reflecting face, consisting of a number of independent unit patterns 40, formed irregularly for reflecting and dispersing light in the light guide plate, and is moreover formed in an arrangement so as to make the pattern density per unit area uniform. <P>COPYRIGHT: (C)2008,JPO&INPIT |
