1. An image display device comprising a housing that includes an operation surface and an optical modulation element that is housed in the housing and that includes an image-forming surface that modulates light to form an image, said image display device comprising:
a holding portion that movably holds the optical modulation element at least in a direction perpendicular to the image-forming surface; and
an adjusting portion that is composed of at least one wire member, one end of the wire member being connected to the holding portion, the other end of the wire member being rotatably attached to the operation surface;
wherein the holding portion includes a movable portion which moves in a direction perpendicular to the image-forming surface by the rotation of the other end of the wire member,
wherein the holding portion includes a first movable plate that includes a supporting portion that supports the optical modulation element, and
wherein the first movable plate includes a hinge that connects the supporting portion with an outer edge of the first movable plate, and when the hinge is deflected, the supporting portion is moved in a direction perpendicular to a plate surface.
