Abstract

PURPOSE:To enable multi-division driving in a range which cannot be realized with a TN liquid crystal by utilizing chiral smectic C (SmC*) and impressing a DC voltage thereto to change the stable state of ferroelectric liquid crystal molecules, then impressing an AC voltage thereto. CONSTITUTION:One of two sheets of polarizing plates 10, 10 of a panel formed by utilizing SmC* is disposed in such a manner than the polarizing direction 5 thereof coincides with the molecular axis direction of the molecules existing in either state of + or -theta and another sheet is placed similarly in the molecular axis direction 3 or with inclination by 90 deg.. The selecting voltage of the polarity corresponding to either of lighting or non-lighting is impressed to the picture element on a certain scanning electrode and thereafter, the selecting voltage of the reverse polarity corresponding to the other is impressed to the desired picture elements on the scanning electrodes when N-pieces of the forward scanning electrodes are selected. The multi-divisions which are not possible with an LCD of a TN type are thereby enabled.
