ABSTRACT:
A liquid crystal device comprising a first substrate on which a first group of belt-shaped electrodes are formed, a second substrate on which a second group of belt-shaped electrodes are formed so as to cross the first group of belt-shaped electrodes, and a chiral smectic liquid crystal arranged between the first and second substrates, wherein a first pretilt angle of the liquid crystal on the first group of belt-shaped electrodes differs from a second pretilt angle of the liquid crystal in the spaces between the belt-shaped electrodes.
