Patent attributes
A head mounted display device includes a scanning section that forms a scan image by scanning a light beam emitted from a light source, a light guiding optical system that guides the light beam emitted from the scanning section, and a deflection member that deflects the light beam guided by the light guiding optical system toward the eye. The light guiding optical system includes an optical correction system in which a first light path length of a light beam from the scanning section to a first end portion on a nose side of the deflection member is longer than a second light path length of a light beam from the scanning section to a second end portion on an ear side of the deflection member, and that corrects scanning distortion in the scan image which cause a virtual image to have different magnifications in a horizontal direction.
