Patent ID: 8164697

Claim:
A liquid crystal display device comprising: a pair of substrates provided in opposing planes, respectively; wherein said liquid crystal display device comprises, on each of said substrates: (i) a transparent electrode; (ii) a vertical alignment film covering said transparent electrode and subjected to a rubbing alignment process; and (iii) an insulating film provided between said transparent electrode and said vertical alignment film; wherein said transparent electrodes overlap each other, and an overlapped area of said transparent electrodes defines a display area; wherein a liquid crystal is sandwiched between said pair of substrates and has a negative dielectric anisotropy Δ∈ and a specific resistance ρ c1 of 1.0×10 12 Ωcm to 1.0×10 15 Ωcm; and wherein a structure including said vertical alignment films, said insulating films and said liquid crystal between said respective transparent electrodes of said pair of substrates is selected to satisfy conditions of T≦5.2×ρ c1 ×1/(1×10 12 ) 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 said transparent electrodes of said pair of substrates and the display image is turned on.
