Abstract
A head-up display device includes: an illumination light source unit configured to emit illumination light; an image forming unit configured to form the image by partial transmission of the illumination light and to emit the image as the display light; and an anisotropic diffusion unit disposed on an optical path between the illumination light source unit and the image forming unit to diffuse the illumination light at an anisotropic diffusion angle. When the image is displayed as a virtual image, the image is defined to have an image up-down axis in a direction along an up-down direction of the vehicle and an image left-right axis perpendicular to the image up-down axis. The diffusion angle in the anisotropic diffusion unit is larger in a direction corresponding to the image left-right axis than in a direction corresponding to the image up-down axis.
