Liquid crystal device, method for driving the same, and projection display and electronic equipment made using the same

摘要

The invention relates to a liquid crystal apparatus which is capable of reducing deterioration of image quality owing to optical cross-talk. The data signal supplied to the data signal line changes within a range of negative polarity data voltage amplitude between a first potential and a second potential at the time of applying negative polarity voltage to the liquid crystal layer. The data signal supplied thereto changes within a range of negative polarity data voltage amplitude between a third potential and a fourth potential at the time of applying positive polarity voltage to the liquid crystal layer. Before supplying this data signal to the data signal line, the data signal line is pre-charged by a negative polarity pre-charging potential and a positive polarity pre-charging potential. The positive and negative polarity pre-charging potentials are set so as to be non-symmetrical to the center potential of the data voltage amplitude. Further, the negative polarity pre-charging potential is set so as to be closer to the first potential than the center potential of the positive data voltage amplitude.
