Abstract
A light guide plate has a light incident surface having an arc configuration and also includes upper and lower surfaces that are respectively provided with a first slope surface and a second slope surface, so that light passes through and is converged by the arc light incident surface and is subjected to total internal reflection at the first and second slope surfaces to have the light guided into the light guide plate and then projecting out through a light exit surface. The light guide plate demonstrates an excellent effect of convergence for light of all angles, so that the light guide plate can be structured thinner without deteriorating light coupling efficiency. Also provided is a backlight module, which involves the light guide plate.
