HEAD-UP DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/093163
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a head-up display device with which the display quality of a display object can be improved. A mirror holder 30 supporting a concave mirror is equipped with a protruding piece 38 that protrudes from the approximate center of the holder width, which is defined along a rotational axis 34, and this protruding piece 38 is moved by a position adjustment means. Stress acting on the mirror holder from the protruding piece is uniform in the left and right directions from the center of the mirror holder. Consequently, twisting at the location of the mirror holder is significantly reduced, so the driver is able to view a display object for which distortion has been suppressed, and the display quality of the display object is improved.
