Abstract: 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.

Abstract: 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.

Abstract: A display device for head-up display forms an image with a view of an object from above in a vertical direction in a space outside the display device for an image which presents an object with a vertical direction. The object includes a reference surface that is a reference of the vertical direction. The display device forms the image so that an observer has a view from the upper part of the reference surface.

Abstract: An optical device includes a light guiding plate which guides lights within the surface parallel to an emission surface, and light converging sections onto which the lights guided by the light guiding plate are incident, each of the light converging sections having an optical surface which allows an emitted light to be emitted from the emission surface in a direction where the emitted light is to be substantially converged on one convergence point or convergence line in space or to be substantially diverged from one convergence point or convergence line in space. The light converging sections are formed respectively along a predetermined line within the surface parallel to the emission surface, and the convergence points or the convergence lines are different from each other among the light converging sections, and an image is formed in space by an aggregation of the convergence points or the convergence lines.

Abstract: An optical device has a light guide plate that guides light in a plane parallel to an emission surface thereof, an optical deflection surface that deflects light entering the light guide plate from a light source that faces a plane parallel to at least the emission surface or the surface opposite the emission surface, so that the light travels along the light guide direction of the light guide plate, and a plurality of light focusing portions. Each of the light focusing portions includes an optical surface whereon the light deflected by the optical deflection surface and guided by the light guide plate is incident, and which causes the emission surface to output emission light that converges substantially on a convergence point or convergence line in a space, or that radiates substantially from a convergence point or convergence line in a space.
