The light incidence surface (11 and 21) is connected to the light exit surface (13 and 23) and the light guide plate bottom surface (15 and 25). The light guide plate (10 and 20) is wedge-shaped. The thickness of the light guide plate (10 and 20) at the end in proximity to the light incidence surface (11 and 21) is greater than the thickness at the end away from the light incidence surface (11 and 21). The light guide plate (10 and 20) is also provided with a wedge-shaped cavity (17 and 27). The wedge-shaped cavity (17 and 27) is provided with a wedge-shaped cavity bottom surface (173 and 273) provided in proximity to the light guide plate bottom surface (15 and 25). A reflective sheet (19 and 29) is provided within the wedge-shaped cavity (17 and 27) of the light guide plate (10 and 20). The reflective sheet (19 and 20) is affixed to the wedge-shaped cavity bottom surface (173 and 273) and the reflective sheet (19 and 29) is provided at the side thereof facing the light exit surface (13 and 23) with a reflective protrusion (191). The light guide plate (10) has a small loss of light energy, is inexpensive to manufacture, and is capable of increasing the brightness of a light.
