An aerial image display device comprising: a display component having a display surface for displaying an image; an imaging component having a first reflecting surface and a second reflecting surface that are arranged perpendicular to each other and perpendicular to an image formation plane of the imaging component, the imaging component being configured to form an aerial image of the image in a display area that is symmetrical with the display surface with respect to the image formation plane; and a first limiter disposed closer to the display component than the imaging component, the first limiter being configured to limit an incident angle of incident light incident on the imaging component, the first reflecting surface and the second reflecting surface being inclined by an angle between 30° and 60° with respect to a median plane that includes a perpendicular of each of the display surface and the image formation plane, characterized in that; the imaging component includes a dihedral corner reflector array, the dihedral corner reflector array including a translucent base component that has a first main face and a second main face that is disposed on an opposite side from the first main face, a plurality of dihedral corner reflectors that are arranged relative to each other on the first main face of the base component, the dihedral corner reflectors each having the first reflecting surface and the second reflecting surface, and a light blocking layer covering a region of the second main face the base component other than regions corresponding to the dihedral corner reflectors; each of the dihedral corner reflectors is a micro mirror formed in a cuboid shape, a top face of each of the dihedral corner reflectors being configured to function as an incident face of the imaging component; and the first reflecting surface and the second reflecting surface are respectively formed on two adjacent side faces (40a, 40b) of each of the dihedral corner reflectors, and disposed perpendicular to each other and perpendicular to the image formation plane. a display component having a display surface for displaying an image; an imaging component having a first reflecting surface and a second reflecting surface that are arranged perpendicular to each other and perpendicular to an image formation plane of the imaging component, the imaging component being configured to form an aerial image of the image in a display area that is symmetrical with the display surface with respect to the image formation plane; and a first limiter disposed closer to the display component than the imaging component, the first limiter being configured to limit an incident angle of incident light incident on the imaging component, the first reflecting surface and the second reflecting surface being inclined by an angle between 30° and 60° with respect to a median plane that includes a perpendicular of each of the display surface and the image formation plane, characterized in that; the imaging component includes a dihedral corner reflector array, the dihedral corner reflector array including a translucent base component that has a first main face and a second main face that is disposed on an opposite side from the first main face, a plurality of dihedral corner reflectors that are arranged relative to each other on the first main face of the base component, the dihedral corner reflectors each having the first reflecting surface and the second reflecting surface, and a light blocking layer covering a region of the second main face the base component other than regions corresponding to the dihedral corner reflectors; a translucent base component that has a first main face and a second main face that is disposed on an opposite side from the first main face, a plurality of dihedral corner reflectors that are arranged relative to each other on the first main face of the base component, the dihedral corner reflectors each having the first reflecting surface and the second reflecting surface, and a light blocking layer covering a region of the second main face the base component other than regions corresponding to the dihedral corner reflectors; each of the dihedral corner reflectors is a micro mirror formed in a cuboid shape, a top face of each of the dihedral corner reflectors being configured to function as an incident face of the imaging component; and the first reflecting surface and the second reflecting surface are respectively formed on two adjacent side faces (40a, 40b) of each of the dihedral corner reflectors, and disposed perpendicular to each other and perpendicular to the image formation plane.
