ABSTRACT:
A liquid crystal device with a compensator made of a layered inorganic compound sheet or film in which a refractive index in the plane and a refractive index in the thickness direction are different from each other. The layered inorganic compound may be smectite group minerals. The layered inorganic compound has a mean particle size of 500 nm or less. The phase retarder is employed in a liquid crystal device.
