摘要： An optical device includes a light-guiding plate and light sources that each emit light to the light-guiding plate. The light-guiding plate has light convergence portions, the light substantially converges at or scatters from a convergence point or line, and an image is formed by a collection of the convergence points or lines, and a light convergence portion causes light to be emitted in directions in which the light substantially converges in or scatters from a range including a point located a first distance apart from the emission surface, and a second light convergence portion causes light to be emitted in directions in which the light substantially converges in or scatters from a range including a point located a second distance, which is longer than the first distance, apart from the emission surface, and the number of first light convergence portions is higher than the number of second light convergence portions.

摘要： An optical device includes one or more light sources and a light-guiding plate that guides light emitted from the light sources in a plane parallel to an emission surface that emits light. The light-guiding plate has light convergence portions that receive guided light and each have optical surfaces that cause light to be emitted from the emission surface in directions in which the light substantially converges at or scatters from one convergence point. The convergence points for the light convergence portions are different from each other. An image is formed on an emission surface side by a collection of the convergence points. First light convergence portions positioned differently from each other along a light-guiding direction of the light-guiding plate cause light to be emitted from the emission surface in different directions in which the light substantially converges at or scatters from the same first convergence point among the convergence points.

摘要： 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.

摘要： A light guide plate, produced from material transparent to visible light, includes a plurality of prisms provided on one surface (a diffusion surface) thereof in a predetermined pattern. The plurality of prisms include a reflection surface that reflects visible light emitted from a light source and entering the light guide plate from an input surface toward another surface (an output surface). Each prism in the plurality of prisms is distributed so that the reflection surfaces of two prisms separated by a predetermined pitch are oriented in the same direction, and the reflections surfaces of two prisms that are closer than the predetermined pitch are oriented in mutually different directions.
