Abstract

A micromirror device comprises a plurality of mirrors arranged on a substrate, an elastic hinge for supporting each mirror to be deflectable, an address electrode having first and second regions arranged across the deflection axis of each mirror, a driving circuit for controlling a deflection of the mirror, and a stopper provided in a position of making contact with the mirror in a deflected state of the mirror. When the mirror makes contact with the stopper, the potential of the mirror or the stopper changes.
