Abstract
A scanning-type display device includes: a light source which emits projection-display laser light; an optical scanning unit which uses the laser light emitted from the light source in scanning; and a light diffusion unit which includes a plurality of light diffusion channels arranged in two dimensions and diffuses the laser light used in scanning by the optical scanning unit. The light diffusion unit is configured so that an angle formed by optical paths extending to an eye of an observer through a pair of adjacent light diffusion channels arbitrarily selected from among the plurality of light diffusion channels becomes equal to or larger than an angle set on the basis of a resolution angle of the eye.
