ABSTRACT:
Disclosed is a liquid crystal display (LCD). An LCD panel is divided into upper and lower panels, and a scanning direction of gate lines of the upper panel is opposite to that of gate lines of the lower panel. The upper panel includes an upper gate line block having a first gate line formed in the horizontal direction and transmits scanning signals, and upper data lines that cross the first gate line and transmit image signals. And the lower panel includes a lower gate line block having a second gate line, and lower data lines that cross the second gate line and are separated from the upper data lines. Upper and lower gate drivers that provide scanning signals to the gate lines of the upper and lower gate line blocks are located on the sides of the upper and lower panels, respectively. The upper and lower gate drivers supply the scanning signals to the gate lines in sequentially opposite directions. According to the present invention, the non-uniform brightness phenomenon can be prevented by making the scanning direction of the gate lines of the upper panel opposite to that of the gate lines of the lower panel.
