ABSTRACT:
A liquid crystal display device is constituted so that liquid crystal having an inherent spontaneous polarization or a spontaneous polarization induced by applying an electric field is interposed between a pixel electrode disposed in matrix and a counter electrode, and a display signal is applied to the pixel electrode through a switching element. In the liquid crystal display device constituted mentioned above, when an electrostatic capacitance of one pixel is C.sub.LC (F), a spontaneous polarization per unit electrode area of the liquid crystal is P.sub.s (C/m.sup.2), a voltage applied between the pixel electrode and the counter electrode is E (V), a pixel electrode area of one pixel is A (m.sup.2), and a storage capacitance for one pixel is C.sub.s (F), they satisfy the following equation;
