Abstract
It is an object to provide an active matrix device which permits enlargement of the area and high-speed response and which serves in place of a semiconductor switch.An active matrix device 35 incorporating scanning-signal electrodes 25 and data-signal electrodes 16 disposed in a matrix configuration and structured such that at least one matrix operating means and a light function device which is operated by the matrix operating means are disposed at intersections of the scanning-signal electrodes 25 and the data-signal electrodes 16, wherein the matrix operating means is mechanically-conductive switch 33 which is operated by static electric force. The mechanically-conductive switch 33 incorporates a thin flexible film 23 which is deflected by static electric stress, a conductive film 29 formed on the thin flexible film 23, a data-signal electrode 16 and a pixel electrode 27a of the light function device. When the thin flexible film 23 is deflected, the conductive film 29 is brought into contact with the data-signal electrode 16 and the pixel electrode 27.
