Abstract: A spatial image display apparatus includes: a display section including a plurality of pixels disposed in a two-dimensional array, the plurality of pixels configured to radiate light rays at different radiation angles with each other respectively so as to form a planar image including a plurality of image points disposed in a two-dimensional array in a space apart from an array face of the plurality of pixels, wherein two or more predetermined number of pixels out of the plurality of pixels radiate the predetermined number of light rays so as to intersect to form one of the image points, and an interval of two adjacent light rays out of the predetermined number of light rays having passed one of the image points is equal to or less than a predetermined observation interval at a predetermined observation position.

Abstract: A floating image display unit according to an embodiment of the technology includes an optical plate and one or a plurality of reflectors. The optical plate includes a plurality of optical elements arranged in a matrix on a substrate having a normal in a Z-axis direction, and each of the optical elements is configured to regularly reflect an entering light beam of a Z-axis direction component and recursively reflect an entering light beam of an XY-axis direction component. The one or the plurality of reflectors are configured to reflect light outputted from a light emitter or a light irradiation target object disposed on rear surface side of the optical plate, thereby causing the light to obliquely enter a rear surface of the optical plate.
