Abstract

See full text

A first stereoscopic image display device includes a light guide plate having a plurality of reflectors and causes an observer to recognize an undistorted stereoscopic image even when the observer views a stereoscopic image from a high angle with respect to a direction normal to the front surface of the light guide plate. In a plan view from a direction vertical to an outgoing surface, when four quadrants are specified for each of the reflectors, the four quadrants taking a position of each of the reflectors as an origin, the four quadrants being divided by two straight lines orthogonal to each other and inclined 45° with respect to a direction in which the incident light is incident on each of the reflectors, light changed in the optical path by each of the reflectors is emitted to a quadrant adjacent to a quadrant on which incident light is incident.
