When the applied voltages are 7 V and 5 V, a transmittance of equal to or more than 50% is obtained when conditions of |2Ps.A|<=|7Clc.A| and |2Ps.A|<=|5Clc.A | are satisfied among the magnitude Ps (nC/cm<SUP>2</SUP>) of the spontaneous polarization per unit area of the liquid crystal material, the electrode area A (cm<SUP>2</SUP>) of the pixels and the capacity of liquid crystal Clc (nF/cm<SUP>2</SUP>) per unit area, and a transmittance of equal to or more than 80% is obtained when conditions of |2Ps.A|<=|4.5Clc.A| and |2Ps.A|<=|3Clc.A| are satisfied thereamong. A sufficiently high transmittance is obtained without the provision of a storage capacitor.
