Abstract:
A micromirror device for an image display apparatus, comprising:a substrate; a pair of first posts protrusively formed on an upper surface of the substrate so as to be separated from each other by a predetermined distance; electrodes formed on the substrate; a supporting plate supported by the first posts and rotatably arranged using a portion supported by the first posts as a hinge point; a second post protrusively formed on the supporting plate; and a mirror supported by the second post for reflecting light incident on one surface thereof, wherein a slope of the mirror can be controlled by an electrostatic attraction between the electrodes and the mirror, and wherein the first posts are formed relatively lower than the second post so that the supporting plate rotates to a maximum displacement point at which the supporting plate contacts the substrate without the edges of the mirror contacting the substrate or the supporting plate so that the mirror is prevented from contacting the substrate or the supporting plate.
