ABSTRACT:
A display system according to the present invention is provided with a projective display unit for projecting a display image of a display device which displays various data, onto a front glass of the vehicle and forming a virtual image of the display image in front of the front glass, and a position adjusting means for adjusting the position of the virtual image formed in front of the front glass by shifting a projective optical axis of the display image extending to the front glass, whereby the whole surface of the front glass in front of the driver can be utilized as a display image projection surface and hence the virtual image of the display image can be formed in a desired position aligned with the line of vision of the driver without obstructing the front sight of the driver.
