ABSTRACT:
A compact liquid crystal optical element for optical modulation and a compact optical device. A liquid crystal optical element for optical modulation is prepared by connecting two transparent substrates, each formed with a transparent electrode and an orientation film, with a sealing member, leaving a clearance between the two transparent substrates. On at least one surface of at least one of these transparent substrates, a diaphragm is formed using a shielding member. With this arrangement, it is possible to provide a more compact liquid crystal optical element than has been conventionally available. At the same time, it is possible to substantially reduce the occurrence of noise. Therefore, it is possible to provide a liquid crystal optical element and an optical device having excellent performance.
