Abstract
A ferro-electric liquid crystal electro-optical device comprising two plates having electrodes, and ferro-electric liquid crystals, for example, chiral smetic crystals, sandwiched between the plates. The inner surface of one of the two plates has a uni-axial alignment characteristic which aligns the liquid crystal molecules in its uni-axial direction. The inner surface of the other plate has a random homogeneous characteristic which aligns the molecules nearly parallel to the plates but does not let the molecules have any predetermined directional characteristic.
