<P>PROBLEM TO BE SOLVED: To save space by reducing a number of components compared with a conventional parallax barrier type stereoscopic display device. <P>SOLUTION: A stereoscopic display device comprises a light source device which emits light for image display to a display section 1. The light source device comprises a light source 2 and a light guide plate 3. The light guide plate 3 comprises a first internal reflection face 3A and a second internal reflection face 3B. The first internal reflection face 3A comprises: a total reflection area 32 which makes a light beam entering with an incidence angle satisfying prescribed total reflection conditions perform total internal reflection; and a scattering area 31 which makes at least a part of the light beam entering with an incidence angle satisfying prescribed total reflection conditions in the total reflection area 32 emit to the outside. The scattering area 31 and the total reflection area 32 can be provided on the second internal reflection face 3B. <P>COPYRIGHT: (C)2013,JPO&INPIT |
