ABSTRACT:
A reflector used in a surface light source comprising a white polyester film in which fine voids are formed and whose apparent specific gravity is in the range of 0.5 to 1.2. The reflectance of the polyester film can be increased by the fine voids. When the reflector having a high reflectance is used in a surface light source having a side light system, a bright scope of, for example, a liquid crystal display easy to see can be obtained.
