Abstract
A light guide panel according to the present invention includes at least one set of mutually opposing incident end surface portions through which light from light sources is introduced, a front surface portion through which light introduced from the set of the incident end surface portions is emanated, a back surface portion positioned on the opposite side to the front surface portion, and many light deflection portions formed on at least one between the front surface portion and the back surface portion. The rate of the light deflection portion per unit area along the other incident end surface portion from the one incident end surface portion is set to be two Gaussian distributions, and the peak of the first Gaussian distribution is biased to the side of the one incident end surface portion, and the peak of the second Gaussian distribution is biased to the side of the other incident end surface portion. Thereby, the amount of light emanating from the center of the light guide panel is relatively increased, and distribution of the amount of light emanating from all the front surface portion of the light guide panel can be made uniform.
