Abstract
The invention relates to a display device (2) for a motor vehicle (1) having a housing, which comprises a projection device (3) arranged in the housing for generating a virtual image (10) on a projection surface which is located outside the housing and observable by an observer, which projection device comprises at least one mirror (6) mounted such that it is pivotable about an axis of rotation (11), which mirror is designed to deflect light (4) output by a light source of the projection device (3) in a deflection position, and having an adjustment device for adjusting the deflection position of the mirror (6) by pivoting about the axis of rotation (11), wherein the adjustment device comprises at least one first shape-memory wire (17), which is coupled to the mirror (6), and therefore the mirror (6) is pivotable about the axis of rotation (11) by a length change of the first shape-memory wire (17). Furthermore, the invention relates to a driver assistance system, a motor vehicle (1) and a method.
