A method of driving a display panel adapted to display a three-dimensional, 3D stereoscopic image in which left-eye images and right-eye images are displayed in a cycle of four image frames, the method comprising: in a first frame: outputting to a pixel unit of the display panel a first data voltage having a first value with respect to a reference voltage (Vcom), and a first data voltage polarity with respect to the reference voltage (Vcom); in a second frame: outputting to the pixel unit of the display panel a second data voltage having a second value with respect to the reference voltage (Vcom) less than the first potential and having data voltage polarity identical to that of the first data voltage in the first frame; in a third frame: outputting to the pixel unit of the display panel a third data voltage having the first value and a data voltage polarity reversed with respect to that of the data voltage in the first frame; in a fourth frame: outputting to the pixel unit of the display panel a fourth data voltage having the second value and having a data voltage polarity reversed with respect to that of the data voltage in the second frame; characterized in that a left-eye data voltage is output to the pixel unit during the first and third frames, and a right-eye data voltage is outputted to the pixel unit during the second and fourth frames, the left-eye data voltage being the first data voltage and the right-eye data voltage being the second data voltage. in a first frame: outputting to a pixel unit of the display panel a first data voltage having a first value with respect to a reference voltage (Vcom), and a first data voltage polarity with respect to the reference voltage (Vcom); in a second frame: outputting to the pixel unit of the display panel a second data voltage having a second value with respect to the reference voltage (Vcom) less than the first potential and having data voltage polarity identical to that of the first data voltage in the first frame; in a third frame: outputting to the pixel unit of the display panel a third data voltage having the first value and a data voltage polarity reversed with respect to that of the data voltage in the first frame; in a fourth frame: outputting to the pixel unit of the display panel a fourth data voltage having the second value and having a data voltage polarity reversed with respect to that of the data voltage in the second frame; outputting to the pixel unit of the display panel a second data voltage having a second value with respect to the reference voltage (Vcom) less than the first potential and having data voltage polarity identical to that of the first data voltage in the first frame; in a third frame: outputting to the pixel unit of the display panel a third data voltage having the first value and a data voltage polarity reversed with respect to that of the data voltage in the first frame; in a fourth frame: outputting to the pixel unit of the display panel a fourth data voltage having the second value and having a data voltage polarity reversed with respect to that of the data voltage in the second frame; a left-eye data voltage is output to the pixel unit during the first and third frames, and a right-eye data voltage is outputted to the pixel unit during the second and fourth frames, the left-eye data voltage being the first data voltage and the right-eye data voltage being the second data voltage.
