LIGHT GUIDE PLATE EQUIPPED WITH OPTICAL DEFLECTION MEMBER AND SIDE LUMINESCENCE BACKLIGHT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light guide plate equipped with an optical deflection member and a side luminescence backlight device.

SOLUTION: The light guide plate includes optical deflection members fitted on a light-irradiating face of an LGP and at least on one of the faces facing the above. The optical deflection members face each other with a normal line perpendicular to a light-incident face as a center, and are positioned so as to be widened from the light-incident face toward an opposite face, and are provided with a first and a second faces perpendicular to the light-irradiating face. With this, optical deflection members with various angles for obtaining a required light irradiation distribution can be arrayed.
