    • A light guide plate includes an incident surface on which light outputted from point light sources is incident and an outgoing surface for outputting light incident from the incident surface. A reflection-and-propagation surface for reflecting light toward the outgoing surface is formed in a back surface opposite to the outgoing surface. The outgoing surface is made up of a propagation region adjacent to the incident surface, a propagation auxiliary region adjacent to the propagation region, a first diffusion-and-propagation region adjacent to the propagation auxiliary region, and a second diffusion-and-propagation region adjacent to the first diffusion-and-propagation region. The propagation region, the propagation auxiliary region, and the first diffusion-and-propagation region control hot spots and bright/dark lines in vicinities of the incident surface, while the second diffusion-and-propagation region controls viewing-angle characteristics of the light guide plate.
