  • Patent number: 8711319
    Abstract: A liquid crystal display device restraining display defects even in a structure having a potential difference between an externally-connected electrode potential and the mean potential of the drive waveform of a liquid crystal material. An electrostatic charge stored in the vicinity of a liquid crystal layer of the liquid crystal display device as a result of the potential difference between an externally-connected electrode potential and the mean potential of the drive waveform of the liquid crystal material is dispersed by employing a capacitor or an arrester connected to ground. Accordingly, discharge of the stored charge is facilitated, and occurrence of display defects is restrained.
