A micromirror device for an image display apparatus in which it is possible to drive a mirror by rotation is provided. The micromirror device according to the present invention includes 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 electrode and the mirror.
