ABSTRACT:
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/cm2) of the spontaneous polarization per unit area of the liquid crystal material, the electrode area A (cm2) of the pixels and the capacity of liquid crystal Clc (nF/cm2) 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.
