PROBLEM TO BE SOLVED: To provide an active matrix type chiral smectic liquid crystal element improved in afterimage, deterioration in alignment with time, burning, etc. SOLUTION: After an asymmetric cell is formed so that a 100 mV or higher switching threshold voltage difference to bistable and different stable states is generated and is reset to a stabler state, gradations are displayed by switching to an unstable state, and an non-holding type display is performed by arranging an non-displaying period before or after a displaying period and applying voltage reversed in polarity instead of voltage applied for the displaying period. |
