PROBLEM TO BE SOLVED: To provide a reflective liquid crystal display device having excellent contrast on visual recognition in the time of light-on and light-off, excellent brightness of display, and preventing displayed images through a light guide plate from being disturbed, to clear them, further preventing lowering of visual visibility of the displayed images caused by a moire phenomenon, and to provide a light guide plate and a surface light source device constituting the reflective liquid crystal display device. SOLUTION: In this light guide plate 1, the incoming light from an incoming side surface 13 outgoes from an under surface 12 through a light outgoing means formed on the upper surface 11, and the incoming light from the under surface 12 is passed through the upper surface 11, further a reflection preventive layer 2a is formed on the upper surface 11. The surface light source device has a light source on the incoming side surface 13 of the light guide plate 1. The reflective liquid crystal display device has a liquid crystal cell equipped with a reflective layer on the under surface side of the surface light source device. |
