摘要： On a substrate are configured piezoelectric elements composed of a mirror device, piezoelectric thin films, electrodes, and elastic members, and application of a voltage to the electrodes causes flexure deformation in the piezoelectric thin films, so that the mirror device is actuated. A plurality of the piezoelectric elements are arranged in parallel with a longitudinal direction thereof, and torsion springs are provided so as to extend in a direction orthogonal to the longitudinal direction and so as to hold the mirror device in connection with the substrate. The mirror device is connected to the piezoelectric elements through strain absorbers. In such a configuration, the torsion springs serve as a rotation axis, and the mirror device is inclined about the rotation axis.

摘要： An actuator of the present invention includes a shape maintaining sheet, a piezoelectric member provided integrally on the shape maintaining sheet, and a pair of electrodes formed to sandwich the piezoelectric member, wherein the shape maintaining sheet is formed of synthetic resin. Since the piezoelectric member is thin, the stiffness is increased by the shape maintaining sheet made of synthetic resin, and thus resonance frequency can be adjusted.

摘要： A projection type liquid crystal display unit has dichroic mirrors capable of dividing a light from a light source into R, G and B components which are guided along respective light paths. Each of at least two of these light paths in provided with an optical system which includes a pair of polarizing plates, a twist nematic liquid crystal and at least one phase plate. The angles of the retardation phase axis of the phase plate and light-interruption axes of the polarizing plates or, alternatively, the retardation of the phase plate is determined so as to improve the light-interruption of the liquid crystal panel in light-interruption mode, thereby enhancing contrast of the display image.
