1. An optical deflector comprising:
a first element substrate including a first transparent substrate, a first transparent electrode located at the first transparent substrate, an interlayer insulating layer covering the first transparent electrode, and a plurality of second transparent electrodes extending in parallel with one another on the interlayer insulating layer; a second element substrate including a second transparent substrate and a third transparent electrode located at the second transparent substrate, the third transparent electrode facing the second transparent electrodes on the first element substrate; a liquid crystal layer disposed between the first element substrate and the second element substrate; and a drive circuit configured to apply signal voltages which are individually defined for the second transparent electrodes and in which a low potential and a high potential are repeated as a whole, to the second transparent electrodes, and to apply a signal voltage at the low potential to the first transparent electrode. |
