Image display device and adjusting mechanism

An image display device comprising a light source, a separating means for splitting a light beam from the light source into light beams having at least three different colors, at least three light modulation panels, guide means for guiding each light beam towards an associated light modulation panel, combination means for combining the light beams modulated by the light modulation panels, and at least one adjusting mechanism for adjusting at least one light modulation panel with respect to the combination means, characterized in that the adjusting mechanism is provided with two plates extending transversely to the light modulation panel, the first plate having at least two points of fixation, each of which is movable in the plane of the plate by means of a parallelogram mechanism, and the second plate having at least one point of fixation which is movable in the plane of the second plate by means of a parallelogram mechanism, each parallelogram mechanism being provided with an associated locking mechanism, the adjusting mechanism being further provided with a bearing plate connected to the points of fixation and supporting the light modulation panel, which bearing plate is movable by means of the two parallelogram mechanisms in a direction extending transversely to the bearing plate and is tiltable about axes extending in the plane of the bearing plate, characterized in that the adjusting mechanism is provided with a supporting plate which extends parallel to the bearing plate and to which the light modulation panel is connected, said supporting plate being movable with respect to the bearing plate in directions extending parallel to the bearing plate, and being tiltable about an axis extending transversely to the bearing plate.
