Liquid crystal display device

Abstract

A liquid crystal display device includes: a pair of substrates each disposed on each opposing plane and having an electrode of a predetermine shape; a vertical alignment film formed covering each of the electrodes of the pair of substrates and subjected to a rubbing alignment process; an insulating film formed between the electrode and the vertical alignment film in each of the pair of substrates and having necessary insulation; and liquid crystal sandwiched between the pair of substrates and having a negative dielectric anisotropy Δε and a specific resistance ρc1 of 1.0×1014 Ωcm to 1.0×1015 Ωcm, wherein a structure between the electrodes is selected to satisfy conditions of T≦5.2×τc1×1/(1×1012) sec and T≦500 sec, where T is a charge resident time until a display image disappears completely after static electricity of 10 kV is applied between the electrodes of the pair of substrate and the display image is tuned on. It is possible to prevent alignment defects to be caused by static electricity generated by rubbing of a liquid crystal display device.
