ABSTRACT:
The present invention relates to obtain an electrooptical device having a high response speed by using a spontaneously polarized ferroelectric liquid crystal. Spontaneously polarized ferroelectric liquid crystal in the smectic-A state is sealed into a proper transparent case. An electric field is applied perpendicularly to a light path direction so as to change the orientation directions of liquid crystal molecules, thereby changing the refractive index distribution. A liquid crystal electrooptical device having both deflection and focusing functions is provided by adjusting the shape of the electrodes while maintaining the polarization state of an input light beam.
