Abstract
A display apparatus for a vehicle comprises a unit for projecting a display pattern provided by a display device onto a projecting face in front of a driver's seat; a unit for visually overlapping an outer landscape in front of a front glass and a virtual image of the display pattern provided by the projecting unit; a first mirror for reflecting light from the projecting unit; and a second mirror for reflecting light reflected from the first mirror on the side of the driver's seat such that the virtual image of the display pattern in front of the second mirror is visualized. The display apparatus for a vehicle may comprise another mirror unit for reflecting the light reflected from the first mirror towards the front glass, the reflected light from the second mirror being reflected by the front glass on the driver's seat side such that the virtual image of the display pattern in front of the front glass is visualized. The display apparatus for a vehicle may comprise a device for adjusting the angular position of the mirror with respect to at least one of the forward-backward direction and the right-left direction.
