Abstract

A front light module includes a light guide plate, a light source and a light redirection film. The light guide plate includes a light incident surface, an inner light outgoing surface and an outer light outgoing surface. The light incident surface is adjoined between the inner light outgoing surface and the outer light outgoing surface. The light source is configured to emit light into the light incident surface of the light guide plate. The light redirection film is located beside the inner light outgoing surface, and is configured to redirect a traveling direction of the light from the light guide plate. An acute included angle between the light after redirected and a normal line of the inner light outgoing surface is less than an acute included angle between the light before redirected and the normal line of the inner light outgoing surface.
