Abstract:
An actuated film display device comprising:a fixed electrode formed by insulatively stacking a plurality of conductive layers different in length, in order of length, while the conductive layers are trued up at one end thereof; a light-shield movable film electrode, which is placed so as to face a surface of the fixed electrode having the shortest one of the conductive layers uppermost thereon, and which has a fixed end fixed at the one end of the conductive layers and a movable end, the light-shield movable film electrode being displaced toward the conductive layers of the fixed electrode by application of a voltage not less than a critical voltage between at least one of the conductive layers and the light-shield movable film electrode, the critical voltage being different with the respective conductive layers different in length; and a potential supply circuit selectively supplying different potentials of the voltage not less than the critical voltage to the conductive layers of the fixed electrode.
