Claim Text:
1. A stereoscopic image display apparatus comprising: a light source unit configured to emit light; a single light guide plate having a single incidence surface through which the light emitted by the light source unit enters the single light guide plate, and an emission surface which is different from the incidence surface and from which incident light is emitted to outside the light guide plate with a propagation direction of the incident light changed; and a spatial light modulator which spatially modulates the light emitted from the emission surface, wherein the light source unit is configured to emit the light to cause the light for a right eye of a viewer to be incident on the single incidence surface in a first direction, the first direction being inclined at a predetermined angle in the emission surface with respect to a direction perpendicular to an alignment direction of the right eye and a left eye of the viewer, the light source unit is configured to emit the light to cause the light for the left eye of the viewer to be incident on the single incidence surface in a second direction, the second direction being different from the first direction and being inclined at the predetermined angle in the emission surface with respect to a direction perpendicular to the alignment direction of the right eye and the left eye of the viewer so as to diverge from the first direction, the light incident on the single incidence surface of the single light guide plate is emitted from the emission surface of the single light guide plate, and an incidence angle of the light being incident on the single incidence surface and an emission angle of the light being emitted from the emission surface are equal.
