Patent ID: 8305313

Claim:
A liquid crystal display apparatus comprising: a plurality of pixels disposed at each intersection of plural pairs of data lines and a plurality of gate lines; a plurality of switches provided to each of the plural pairs of data lines supplying a positive image signal to one data line of a pair of data lines and a negative image signal to the other data line of the pair of data lines with respect to each pair of the plural pairs of data lines sequentially one by one; and driver means in the horizontal and vertical directions for driving the plurality of switches in the horizontal direction by each pair of data lines within a horizontal scanning period and for selecting the plurality of gate lines in the vertical direction at each horizontal scanning period; wherein each of the plurality of pixels is provided with: a liquid crystal element having a liquid crystal layer sandwiched between a pixel driving electrode and a common electrode confronting with each other; a first sampling and holding means for sampling the positive image signal and holding a voltage of the sampled positive image signal for a prescribed period of time; a second sampling and holding means for sampling the negative image signal and holding a voltage of the sampled negative image signal for the prescribed period of time; and a switching means for switching a positive image signal voltage held in the first sampling and holding means and a negative image signal voltage held in the second sampling and holding means in a prescribed period shorter than a vertical scanning period and supplying the positive and negative image signal voltages alternately to the pixel driving electrode.
