Abstract: A light path adjustment mechanism includes a bracket, a light valve, a carrier, a first axis, a second axis and an optical plate member. A surface normal of a surface of the light valve crosses the bracket to define an intersection closest to the surface of the light valve, and the bracket has an end point furthest from the intersection measured in the direction of the surface normal. A distance between the intersection and the surface measured in the direction of the surface normal is smaller than a distance between the intersection and the end point measured in the direction of the surface normal.
