Abstract

모노몰프형 액츄에이터를 이용하는 투사형화상표시장치의 광로조절수단에 관한 것이다.A light path adjusting means of a projection image display device using a monomorphic actuator.

모노몰프형 액츄에이터는, 기판(31)과, 기판(31)상에 반도전 압전성 물질로 형성되는 변형부(33)와, 변형부(33)의 일측면에 형성된 신호전극(35)과, 신호전극(35)이 형성된 변형부(33) 측면의 반대 측면에 형성되는 접지전극(37)과, 변형부(33)의 상측면에 형성되는 반사경(39)을 구비한다.The monomorphic actuator includes a substrate 31, a deformable portion 33 formed of a semiconductive piezoelectric material on the substrate 31, a signal electrode 35 formed on one side of the deformable portion 33, and a signal. A ground electrode 37 formed on the side opposite to the side of the deformable portion 33 on which the electrode 35 is formed, and a reflecting mirror 39 formed on the upper side of the deformable portion 33 are provided.
