Abstract
A mirror device comprises: a plurality of electrodes disposed on a substrate; a hinge connected to at least one of the electrodes; a mirror connected to the hinge and corresponding to at least one of the electrodes. The mirror device further comprises a barrier layer is disposed between the hinge and mirror, and/or between the hinge and electrode. Also noted is a mirror device production method for producing such-configured mirror device. Furthermore, this invention discloses a projection apparatus implemented with a mirror device manufactured and assembled according to the configuration as described.
