A display device includes a transparent substrate having a display region with a plurality of scanning signal lines and video signal lines intersecting thereon, a first terminal formed outside the display region connecting to a first terminal wiring and a second terminal wiring connected to a semiconductor chip, and an inverted staggered thin film transistor. Thus, as the vibration absorber vibrates in response to vibration of the frame, in a direction to offset the vibration if the frame, the vibration of the frame can be reduced. The identity selector directs the release of a user identity as a security token to satisfy the requirements of a security policy. The method displays the selected transmission path on a monitor.
