An exemplary liquid crystal display device (1) includes a first substrate (3), a second substrate (2) facing the first substrate, and a liquid crystal layer (4) sandwiched between the first substrate and the second substrate. The first substrate includes a plurality of scan lines (11); a plurality of first and second parallel data lines (12, 22) orthogonal to the scan lines; a plurality of first and second thin film transistors (14, 24), positioned near a crossing of a corresponding scan line and a corresponding first data line, respectively; a plurality of first and second pixel electrodes (15, 25) electrically coupled to the first and second thin film transistors, respectively; a plurality of first and second static display units (19, 29) for providing voltage to the first and second pixel electrodes in a static display mode.
