A plurality of gate lines(100) simultaneously receive a scan pulse for at least every two lines. A plurality of data lines(200) intersect the gate lines, and receive a data signal. Pixels(300) are defined by each gate line and at least two of the plurality of data lines. Adjacent pixels having the gate line as a boundary are formed as a zigzag shape along a direction of the data lines. The pixel is defined by one of the gate lines simultaneously driven for at least every two lines, and two data lines. Each pixel of an ith horizontal line (i is a natural number) is driven by a scan pulse from an ith gate line and a data signal from a first data line between the two data lines. Each pixel of an i+1th horizontal line is driven by a scan pulse from an i+1th gate line and a data signal from a second data line between the two data lines.
