Abstract: A head-up display adapted for use with a windshield or a flat combiner includes an image-generating unit, a curved mirror and a concave mirror. The image-generating unit is operable to generate a light image propagating along a first optical path. The curved mirror is arranged downstream of the first optical path to form a first reflected light image propagating along a second optical path. The concave mirror is arranged downstream of the second optical path to form a second reflected light image propagating along a third optical path to be reflected onto the windshield or the flat combiner. The third optical path extends inclinedly relative to the second optical path and intersects with the first optical path.
