ABSTRACT:
In an edge-light-type surface light source device, a reflecting means for reflecting light is provided on portions of a first frame that surround each linear light source and other reflecting means are provided on portions of a second frame that are opposed to a reflection surface of a light guide plate and each linear light source, respectively. As a result, lamp reflectors and a reflection sheet of a conventional surface light source device can be omitted. The reflecting members, which are made of a high-reflectance metal such as silver, are formed by common evaporation, a method of applying paste containing fine metal particles, a method of a thin metal plate integrally with each of the first and second frames.
