Abstract:
A liquid crystal apparatus comprising:a liquid crystal panel comprising a plurality of pixels which are arranged along a plurality of rows and columns and each of which comprises a pair of electrodes opposed to each other and a liquid crystal disposed between the pair of electrodes, horizontal scanning lines connecting each row through a common wiring, and vertical data lines connecting each column through a common wiring; a drive circuit comprising a vertical scanning circuit for driving said horizontal scanning lines and a horizontal scanning circuit for driving said vertical data lines, so that said vertical scanning circuit is driven to select a row, and said horizontal scanning circuit is driven to supply the plurality of pixels along the selected row through said vertical data line with a data signal voltage; and a control circuit for controlling said drive circuit during an odd field period and an even field period, such that voltage polarities of the data signal voltages supplied to the pixels adjacent to each other along the selected row are opposite to each other, so that voltage polarities of the data signal voltages supplied to the pixels adjacent to each other along a column are opposite to each other, the voltage polarity of the data signal voltage supplied to one pixel is inverted per each field period, and the voltage polarity of the data signal voltage supplied to one pixel is further inverted per predetermined number n of frames.
