Abstract
An optical device may include a flat optical member; a reinforcement member which is bonded to a back side of the optical member and demonstrates stronger rigidity in a center area thereof than two side portions thereof when curved in a thickness direction in a first direction within an in-plane direction; and a driving device which switches a shape of the optical member together with the reinforcement member between a flat state and a curved state in which the optical member is curved in the first direction.
