Abstract
A light guide plate includes a light incident section and a light guiding section. The light incident section includes a light incident surface configured to receive light beams emitted from a light source, a top surface adjacent to the light incident surface, a first bottom surface oppose to the top surface. The light guiding section includes a main light emitting surface, a connecting surface connecting the main light emitting surface with the top surface, a second bottom surface opposite to the main light emitting surface and connecting with the first bottom surface, and a contacting surface connecting with the main light emitting surface and the second bottom surface. A step is formed at a junction of the light incident section and the light guiding section, and the connecting surface and the top surface define an accommodating space.
