ABSTRACT:
A head-up display device includes a light source, a display unit for producing display virtual images including an alarm display image, a mirror for reflecting the light to show the alarm display image in a field of front view of a driver, at least one on-vehicle device that the driver operates, a visual-line shift detecting means and a display position shifting means. The mirror reflects the light representing the alarm display image so that a driver can see the alarm display image in a display area that is set on one of a front windshield and a combiner in front of the driver and in a field of front vision of the driver. The visual-line shift detecting means detects a visual line shift of the driver from a usual forward visual range of the driver toward the on-vehicle device that the driver operates. The display position shifting means shifts positions of the display area to a position between the usual forward visual range and a portion/part, of the on-vehicle device at operation, which the driver watches during the operation when the visual-line shift detecting means detects the visual line shift from the usual forward visual range toward the on-vehicle device.
