ABSTRACT:
There is disclosed a ferroelectric liquid crystal device such as a chiral smectic liquid crystal device which is suitable for a gradation display. A chiral smectic liquid crystal is sandwiched between electrode substrates and is driven by an electric field which is applied through electrodes formed on the electrode substrates. At least one of the opposite electrode substrate surfaces periodically has a shape like a stripe-shaped rib. Liquid crystal molecules are oriented so that the normal lines of a plurality of layers which are constructed by a plurality of molecules and are arranged in a uniform direction when they are projected onto the electrode substrate surfaces perpendicularly cross the longitudinal direction of the stripe-shaped rib.
