    Abstract: In a liquid crystal device, an electrode is provided between a pixel area of a first substrate and a seal material, and an AC signal is applied to the electrode where a potential with respect to a common potential applied to a common electrode as a reference potential is alternately switched between a positive polarity and a negative polarity. For the AC signal, a length of a positive polarity period where a polarity becomes positive with respect to the common potential and a length of a negative polarity period where a polarity becomes negative with respect to the common potential are different. When anionic impurities of a liquid crystal layer are focused, a positive polarity period length is greater than a negative polarity period length. When cationic impurities of the liquid crystal layer are focused, a negative polarity period length is greater than a positive polarity period length.
