Abstract: An aerial display apparatus includes: a light source unit that emits light; a display device that transmits the light from the light source unit to display an image; a light control device that transmits the light from the display device to emit the light such that light intensity of the light has a peak in a direction oblique to a normal direction that is perpendicular to a first direction within a principal plane of the display device; and a mirror device that reflects the light from the light control device to display an image in air on a side opposite to the light control device. The mirror device includes a plurality of optical elements each having a hexahedron shape. Each of the plurality of optical elements includes first and second reflection surfaces that reflect light. Each of the first and second reflection surfaces is placed obliquely to the normal direction.

Abstract: An aerial display apparatus includes: a display device configured to display an image; and an optical device arranged to receive light from the display device and reflecting the light from the display device to a side opposite to the display device. The optical device includes a planar base member, and a plurality of optical elements provided below the base member as viewed from a viewer, each extending in a first direction and aligned in a second direction orthogonal to the first direction. Each of the optical elements has an incident surface and a reflection surface which are inclined with respect to a normal direction of the base member and are in contact with each other.

Abstract: An aerial display apparatus includes: a display device displaying an image; and a prism device reflecting light from the display device and causing an image to be displayed in an aerial space on a side opposite to the display device. The prism device includes a plurality of prism elements arranged in a horizontal plane. Each of the prism elements is formed of a hexahedron and includes a first and a second refraction surfaces refracting light and a first and a second reflection surfaces reflecting light. The first refraction surface corresponds to a bottom surface of the hexahedron and is inclined with respect to a first direction parallel with the horizontal plane. The second refraction surface corresponds to a top surface of the hexahedron and is inclined with respect to the first direction.
