1. A liquid crystal device, comprising a plurality of pixels each comprising a pair of opposing electrodes, and a ferroelectric smectic liquid crystal disposed between the opposing electrodes so as to develop bistable states,wherein at least one of the opposing electrodes is provided with stripe-shaped unevennesses extending in a direction such that said direction forms acute angles with two molecular orientation directions in the bistable states of the liquid crystal, the smallest one of the acute angles in terms of absolute value not exceeding a cone angle of the ferroelectric liquid crystal in chiral smectic phase.
