A liquid crystal apparatus is constituted by a liquid crystal device including a pair of substrates having thereon a group of scanning electrodes and a group of data electrodes intersecting the scanning electrodes so as to form an electrode matrix, and a liquid crystal disposed between the substrates so as to form a pixel at each intersection of the scanning electrodes and the data electrode assuming an ON-state and an OFF-state; scanning signal application means for sequentially applying a scanning signal to the scanning electrodes; data signal-application means for applying data signals including a first data signal and a second data signal selectively to the data electrodes in synchronism with the scanning signal, and control means for periodically switching between a first drive mode of using the first and second data signals for providing the ON- and OFF-states, respectively, of the pixels and a second drive mode of using the first and second data signals for providing the OFF- and ON-states, respectively, of the pixels. The liquid crystal apparatus is effective for suppressing a change in drive waveform frequency depending on a display pattern to suppress the occurrence of crosstalk thereby.
