 a plurality of support portions formed on the insulating layers; and thin flexible films and second scanning-signal electrodes disposed opposite to the first scanning-signal electrodes and laminated to be supported at the top ends of the support portions; and conductive films which are disposed opposite to the data-signal electrodes and the pixel electrodes such that contact is permitted through gaps and which are provided for the thin flexible films. In the foregoing active matrix device, when the potential of the second scanning-signal electrode has the same potential as that of the first scanning-signal electrode, the thin flexible film is not supplied with the static electric force. Thus, the thin flexible film is not deflected. Therefore, the resistance between the data-signal electrode and the pixel electrode is infinitely large. Thus, the non-conductive state can be maintained. When the potential of the second scanning-signal electrode is different from that of the first scanning-signal electrode, the thin flexible film is deflected by the static electric force. As a result, the conductive film is brought into electrical contact with the data-signal electrode and the pixel electrode disposed below the thin flexible film in the direction of the deflection of the thin flexible film. As a result, the data-signal electrode and the pixel electrode are conducted to each other. When the voltage of each of the scanning-signal electrode is made to be zero, the thin flexible film is moved to the original position owning to the elastic force. As a result, the data-signal electrode and the pixel electrode are again brought to the non-conductive state.
