Abstract: PURPOSE: To provide a fine pixel plane display which can represent static or dynamic video by using an optical switch, utilizing an electrostatic microactuator manufactured only by a semiconductor process. CONSTITUTION: A shutter-moving element 14 at an arbitrary position in a frame 15 is electrostatically charged in a belt-like shape by applying a select electrode 3 and a signal electrode 2 with voltages which are respectively higher and lower than the voltage of a common electrode 4. When an equilibrium state is reached, the voltage applied to the select line is inverted in polarity, in order and then the electric charges of the select electrode 3 change momentarily, but electric charges which accumulated on the side of the moving element 14 are unable to migrate immediately because of disturbance by the resistance. Consequently, a driving for which moves the moving element 14 to the right is generated, together with a repulsive force between the moving element 14 and select electrode 3, so that the shutter-moving element 14 moves to the right side.
