Abstract
There is provided a spread illuminating apparatus in which its components are reliably fixed and efficiency of light emission is improved. Frame sub-assemblies for covering peripheral portions of upper and lower surfaces of a transparent substrate and upper, lower and end surfaces of light reflection members are provided. The frame sub-assemblies are made of a metal plate and bent to be approximately U-shaped in section and the portions thereof covering the central portion of the transparent substrate, namely, covering the observation surface of the spread illuminating apparatus are cut away. The frame sub-assemblies are configured so as to constitute upper and lower halves, respectively, of a so-called picture frame, and each include a stopper for holding a spot-like light source in a predetermined position with respect to a light conductive member and stoppers for holding the transparent substrate in position with respect to a longitudinal direction of the light conductive member. Openings and projections are provided and engaged with each other to couple the frame sub-assemblies.
