An LCD device includes a plurality of first data lines, a plurality of second data lines, a plurality of display units, a source driver and a gate driver. Each of the second data lines is disposed between two corresponding first data lines, while each display unit is coupled to a corresponding first data line and a corresponding gate line or to a corresponding second data line and a corresponding gate line. The source driver is coupled to the plurality of first data lines and the plurality of second data lines for providing a plurality of data signals. Each of the data signals is outputted to a corresponding first data line during a first period in a write period, and outputted to a corresponding second data line during a second period in the write period.
