ABSTRACT:
An electro-optical device is disclosed. The device comprises a first substrate provided with an electrode and a lead thereon, a second substrate provided with an electrode and a lead thereon, a liquid crystal composition exhibiting ferroelectricity, and a means for orienting the liquid crystal composition at least in its early stage. The liquid crystal composition and the means for orienting the liquid crystal composition at least in its early stage are provided between the first and second substrates, and the product (.DELTA.nd) of the value of the optic anisotropy (.DELTA.n) of the liquid crystal composition and the thickness (d) of the liquid crystal composition is adjusted to 500 to 650 nm.
