Abstract:
1. A display device comprising: an object image generator that generates an object image; and an imaging element that has an element surface tilted with respect to an image generation surface of the object image generator, reflects light emitted from the object image located at one side of the element surface twice, and forms the object image as a real image in a plane-symmetrical location with the element surface in a space at the other side of the element surface, wherein a diffusion angle of the light from the object image generator toward the imaging element is limited within a predetermined angle range; wherein a diffusion angle limiting member that limits the diffusion angle of the light from the object image generator within the predetermined angle range is provided between the object image generator and the imaging element, wherein the diffusion angle limiting member includes a lens array in which plural unit lenses are arranged in one direction, and gain characteristics of the lens array are relatively wider in one direction of the unit lenses and relatively narrower in the other direction of the unit lenses.
