Display device

A display device comprising:

• a display panel comprising:
• a plurality of gate lines which extends in a first direction;
• a plurality of data lines which extends in a second direction different from the first direction;
• and
• a plurality of sub-pixels, wherein each of the sub-pixels is connected to a corresponding gate line of the gate lines and a corresponding data line of the data lines;
• a gate driver configured to drive the gate lines;
• a data driver configured to apply a gray-scale voltage to the data lines;
• and
• a timing controller configured to generate a plurality of control signals and to apply the control signals to the gate driver and the data driver,
• wherein
• a unit pixel of the display panel is defined by an even number of adjacent sub-pixels among the sub-pixels,
• each of the data lines is connected to corresponding sub-pixels of the sub-pixels,
• the data driver inverts a polarity of the gray-scale voltage every two data lines, and
• two adjacent sub-pixels in the unit pixel are applied with gray-scale voltages having different polarities.
