Patent ID: 8179509

Claim:
A manufacture method for a liquid crystal display device using a low duty ratio driving method with a duty ratio not smaller than 1/16, comprising: preparing a first substrate having a first electrode of a predetermined shape; preparing a second substrate having a second electrode of a shape different from said predetermined shape, said second electrode having signal line electrodes smaller in number than signal line electrodes of said first electrode; forming an insulating film having necessary insulation on each of said first and second electrodes; forming first and second vertical alignment films above said first and second substrates, respectively, said first and second vertical alignment films covering said first and second electrodes, respectively; executing a rubbing process only for said second vertical alignment film; and disposing said first and second substrates facing each other, and disposing liquid crystal having a negative dielectric constant anisotropy between said first and second substrates; wherein a specific resistance of said liquid crystal is 1.0×10 12 Ωcm to 1.0×10 14 Ωcm; and wherein at least said second vertical alignment film is made of alignment film material satisfying a condition of 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 first and second electrodes and the display image is turned on.
