Abstract:
A liquid crystal display device, comprising:a first substrate including a plurality of odd data lines and even data lines and a plurality of scan lines, the plurality of odd and even data lines being substantially perpendicular to the plurality of scan lines;a second substrate opposite the first substrate, the second substrate including a plurality of odd-numbered common electrodes and even-numbered common electrodes disposed substantially in parallel with the plurality of odd and even data lines, respectively;a clock signal generator producing a first clock signal and a second clock signal, a phase of the first clock signal being 180-degrees from that of a phase of the second clock signal;a common voltage generator applying a first common voltage to the odd-numbered common electrodes disposed on the second substrate, and a second common voltage to the even-numbered common electrodes disposed on the second substrate; anda data driver connected to the plurality of data lines through one side of the first substrate, the data driver including a latch circuit having a plurality of output terminals each connected to a respective one of the data lines through a respective gate, respective gates connected to the odd data lines receiving the first clock signal to output first pixel driving signals having a predetermined polarity to the respective odd data lines, respective gates connected to the even data lines receiving the second clock signal to output second pixel driving signals having a reverse polarity relative to the first pixel driving signals to the respective even data lines.
