1. A light guide plate for presenting a stereoscopic image via parallax, the light guide plate comprising:
a plurality of deflectors arranged in rows parallel to an incidence surface through which light from a light source enters the light guide plate, the light totally reflecting inside the light guide plate while being guided therethrough, the plurality of deflectors comprising a reflection surface for reflecting and causing an emission surface to emit said light, wherein
the reflection surfaces in a row of the plurality of deflectors are all oriented in the same direction with the orientation of the reflection surfaces changing for each row in accordance with distance from the incidence surface.
