摘要： An optical device includes: a light guide plate; a first light emission part provided in a first region of the light guide plate, the first light emission part having optical surfaces that cause the light incident thereon to exit from a first emission surface and a second emission surface opposite the first emission surface; and a second light emission part provided in a second region of the light guide plate, the second light emission part having optical surfaces that cause the light incident thereon to exit from the first emission surface and the second emission surface. The optical device configured to control the luminous flux from the first and second emission surfaces via the optical surfaces in the first and second light emission parts to thereby control how leaked light is perceived by an observer on the opposite side of the emission surface of the light guide plate.

摘要： A light-guiding plate of an optical device has first light convergence portions and second light convergence portions. The light convergence portions each have optical surfaces that cause light to be emitted from an emission surface in directions in which the light substantially converges at or scatters from one convergence point or one convergence line, the convergence points or lines for the light convergence portions are different from each other, first and second images are formed by a collection of the convergence points or lines of the first and second light convergence portions, respectively, and in a case where an image is projected to a plane perpendicular to the emission surface and parallel to a light-guiding direction of the light-guiding plate, the first and second light convergence portions cause light to be emitted from the emission surface at a first angle and at a second angle, respectively.

摘要： An optical device includes a light-guiding plate that guides light in a plane parallel to an emission surface that emits light, and a sensor for detecting an object located on an emission surface side using light that passes through a back surface opposite to the emission surface and through the emission surface. The light-guiding plate has light convergence portions that receive light guided by the light-guiding plate 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 or one convergence line in a space, and the convergence points or the convergence lines for the light convergence portions are different from each other, and an image is formed in the space on the emission surface side by a collection of the convergence points or the convergence lines.

摘要： 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.

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： 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.
