Abstract: PURPOSE: A method for producing a thin film typed optical path controller is provided to improve the stability of a mirror by preventing an event separated the mirror from a post. CONSTITUTION: A thin film typed optical path controller contains an active matrix(100), a supporting element formed in a upper part of the active matrix(100), an actuator(210) formed in a upper part of the supporting element and a mirror(260) formed in a upper part of the actuator(210). In the thin film typed optical path controller, a first signal transferred from the outside is fed to a lower electrode(180) through a MOS transistor(120) embedded in the active matrix(100), a drain pad and a via contact(280) of a first metal layer(120) and a second signal is fed through a common electrode line(240) from the outside in a first and a second upper electrodes. The mirror(260) to reflect light projected from a source of light is inclined with the actuator because the mirror is formed in the upper part of the actuator by supporting with a post(250). Therefore, the mirror(260) reflects the projected light at the certain angle and the reflected light makes a picture on a screen by passing a slit.
