  • Head-up display device
    Patent number: 11099383
    Abstract: The present invention provides a head-up display device wherein a light shielding part for preventing a washout phenomenon is prevented from shining. A head-up display according to the present invention, in which a display unit for emitting display light (L) is housed in a case and the upper portion of the display unit is covered by the light shielding part, has strip-shaped protrusion parts formed on the bottom surface of the light shielding part (42). With this constitution, the strip-shaped protrusion parts prevent the scattered light (SL) resulting from the light (L) output from the display unit from illuminating the bottom surface of the anti-washout light shielding part, thereby preventing the bottom surface from being displayed as a virtual image.
