Abstract
A liquid crystal material is used in which the maximum angle of the optical axis change by liquid crystal molecule when a voltage of one polarity is applied is larger than 45 degrees and a condition of |2Ps·A|>|5(V)Clc·A| is satisfied where Ps (nC/cm) is the magnitude of the spontaneous polarization per unit area, A (cm) is the electrode area of the pixel and Clc (nF/cm) is the liquid crystal capacity per unit area. The transmittance in the liquid crystal part is increased and excellent display can be performed without the provision of a storage capacitor. Consequently, the storage capacitor is unnecessary, so that the aperture ratio of the liquid crystal panel can be increased.
