Abstract:
1. A liquid crystal device, comprising: M rows of scanning lines, wherein M is an integer equal to or greater than 2, and N columns of data lines, wherein N is an integer equal to or greater than 2; M×N number of switching element respectively connected to one of the M rows of scanning lines and one of the N columns of data lines; M×N number of pixel electrodes respectively connected to one of the M×N number of switching element; M rows of opposite electrodes arranged oppositely to respective rows of the M×N number of pixel electrodes through a liquid crystal layer; a scanning line driving circuit configured to supply a scanning signal including a scanning period for sequentially selecting at least one of the M rows of scanning lines to the entire M rows of scanning lines in each of a plurality of subfields defined by dividing one field; a signal control circuit configured to convert a data signal to a binary signal in each of the subfields; a data line driving circuit configured to supply a binary voltage to the N columns of data lines based on the binary signal from the signal control circuit; and a polarity inverting circuit configured to invert a polarity of a voltage applied to the liquid crystal layer in synchronization with the scanning period by changing a voltage supplied to an opposite electrode of a row corresponding to the selected scanning line in each of the subfields.
