LIGHT DEFLECTOR, LIGHT DEFLECTION ARRAY, AND PICTURE PROJECTION DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light deflector that is easy to control the angle of deflection of a mirror, that is fast in response speed and that is driven by a lower voltage. SOLUTION: A planar member 104 having no fixed end is provided with a light reflection area on the upper face and composed of an electrically conductive member. A fulcrum member 103 having the apex is provided on the upper face of a substrate 101 and made to serve as a fulcrum when the planar member 104 is displaced. On the substrate, a plurality of electrodes 401 opposing the conductive layer of the planar member 104 are installed and arranged such that the working direction of line of electric force generated by a voltage applied to the plurality of electrodes becomes nearly the same as the displaced face direction of the planar member.
