ABSTRACT:
Thin film AMA is disclosed. The thin film AMA has an active matrix, a supporting member, actuating parts and a reflecting member. The supporting member has a supporting line, a rectangular ring-shaped supporting layer, anchors. Insulating members are formed from top electrodes to the supporting layer. The anchors supporting the actuating parts are formed perpendicular to the actuating parts. The initial tiltings of the actuating parts are prevented because the stress concentration line doesn't generated. Therefore, the desired reflection angle of the reflecting member may be regular, so the light efficiency is enhanced and the quality of the picture projected onto the screen is increased. Also, the electrical shorts generated between the top electrodes and the bottom electrodes may be prevented by the insulating members, so point defects of pixels are effectively decreased.
