Abstract:
Provided is a liquid crystal display device having excellent display characteristics in a display mode that uses a vertical electric field and a horizontal electric field. This liquid crystal display device is provided with a first substrate and a second substrate provided facing each other and a liquid crystal layer sandwiched between the first and second substrates. The liquid crystal layer includes liquid crystal molecules having negative dielectric anisotropy. The first substrate is provided with a plate shaped first common electrode, an insulating film, and pixel electrodes, which are provided in a layer different from the first common electrode via the insulating film, and the pixel electrodes have a comb shaped structure. The second substrate is provided with a plate shaped second common electrode and a film formed by having an alignment treatment applied to a vertical alignment film that aligns the initial orientation of the liquid crystal molecules vertically. During the highest gradation, the difference in electric potential between the first common electrode and second common electrode is set to be larger than the difference in potential between the first common electrode and the pixel electrodes.
