    摘要： 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.

    摘要： Fingerprint-erasing cured films for rendering fingerprint depositions on various surfaces quickly less visible, or invisible; a manufacturing method therefor; a display or touch panel using the same; and electronic devices using these are provided. A liquid coating film including a solvent and a polymerizable resin composition curable by an activating energy beam is formed. In a state of the solvent being included within the film, the film is cured to form a cured film containing the solvent, preferably using a release material whose surface has undergone matte processing; and the solvent is evaporated in a subsequent drying step, whereby a cured film with a multitude of micropores on the surface is formed. Fingerprint soiling is rendered not readily visible or invisible. By using the cured film, there are obtained displays, touch panels, and electronic devices having fingerprint-erasability. To improve fingerprint-erasability, adding a water-absorbent compound to the film composition is preferable.
