Patent ID: 7417778

Claim:
A light deflector comprising: a substrate; a plurality of control members, wherein stoppers are provided at upper parts of the control members and the control members are provided at a plurality of end parts of the substrate; a support for each control member; a fulcrum member including a vertex part and provided at an upper surface of the substrate; a plate shape member supported by the fulcrum member, and having a light reflection area, the plate shape member not having a fixed end, the plate shape member including a conductive material layer having conductivity, the plate shape member being movably arranged in a space formed between the substrate, the fulcrum member, and the stoppers, a plurality of electrodes provided on the substrate to face the conductive material layer of the plate shape member, wherein the plate shape member is inclined around the fulcrum member by an electrostatic force from the plurality of electrodes, wherein each support is divided into portions so that contact between the support and respective plate shape member is reduced as the plate shape member moves in inclination, and wherein the support has a quadrangle form.
