Abstract:
A light modulation element for performing electromechanical operation of generating a first electromechanical force for a needle for displacing the needle, thereby changing a transmission factor of light, said light modulation element comprising:drive means for generating or canceling a second electromechanical force for the needle in a direction different from that of the first electromechanical force so as to hold or cancel the displacement state of the needle, wherein the directions of the first and second electromechanical forces are substantially orthogonal to each other; wherein the directions of the first and second electromechanical forces are selected from the group consisting of the direction of the first electromechanical force is substantially horizontal and the direction of the second electromechanical force is substantially vertical, and the direction of the first electromechanical force is substantially vertical and the direction of the second electromechanical force is substantially horizontal.
