<p><P>PROBLEM TO BE SOLVED: To provide an optical deflector wherein the wave face of deflected light is not disturbed and which has high light utilizing efficiency and has no mechanically moval part, and to provide an optical scanner. <P>SOLUTION: The optical deflector is provided with a pair of transparent substrates 11A and 11B disposed so that transparent electrodes 12A and 12B formed on the surfaces of the transparent substrates 11A and 11B, respectively, are opposed to each other and a liquid crystal 14 whose molecular direction is arranged at a prescribed angleθto a light incident surface of the transparent substrate 11B and which is stored between the transparent substrates 11A and 11B. At least one of the transparent electrodes 12A and 12B opposed to each other is formed by using a high resistance film, electricity supplying electrode parts 15A and 15B are provided at the transparent electrode 12B formed by using the high resistance film and the electricity supplying electrode parts 15A and 15B are provided with power sources 16A and 16B applying alternating voltage, respectively. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
