Liquid crystal display device and method for driving the same

A liquid crystal display device has odd- and even-numbered rows of pixels sequentially and repeatedly arranged on a substrate in the horizontal direction, alternate rows being shifted horizontally, first and second groups of data lines for dividing the odd and even-numbered rows of pixels, respectively, into first sub-pixels and second sub-pixels and partitioning the even and odd-numbered rows of pixels, respectively. First and second groups of data lines are alternately arranged on the substrate in the vertical direction, for supplying data signals to the first and second sub-pixels, respectively, through switching devices disposed in each sub-pixel. Gate lines arranged on the first substrate in every two row of pixels in the horizontal direction, for supplying pulse-type scan signals to row units of the first sub-pixels and the second sub-pixels, and common voltage lines are arranged between the gate lines.
