Liquid crystal device, method of driving the same and electronic apparatus

A method of driving a liquid crystal device that includes a plurality of scanning lines, a plurality of data lines, and a plurality of pixel circuits, wherein the plurality of pixel circuits are provided at positions corresponding to intersections of the scanning lines and the data lines, wherein each of the plurality of pixel circuits includes a liquid crystal element that has a first electrode, a second electrode supplied with a reference electric potential, and a liquid crystal held between the first electrode and the second electrode, wherein an alignment state for the liquid crystal includes a first alignment, which is an initial state, and a second alignment, which is used for display, wherein a predetermined voltage needs to be applied to maintain the second alignment, the method comprising:

• driving the liquid crystal device in a display mode in which an image is displayed and a non-display mode in which no image is displayed;
• in the display mode, selecting the plurality of scanning lines in a predetermined order every unit period and supplying the pixel circuits corresponding to a selected one of the scanning lines through the data lines with writing voltages;
• in the non-display mode, selecting the plurality of scanning lines in a predetermined order every unit period and supplying the pixel circuits corresponding to a selected one of the scanning lines through the data lines with the predetermined voltage, of which polarity is inverted in a period of integral multiple of the unit period using the reference electric potential as a reference;
• and
• setting the length of the unit period longer in the non-display mode than in the display mode.
