The driving method is applied to the liquid crystal display 20 described above, and the following description of the driving method will be described by taking the first row of pixels in the second row on the liquid crystal display panel 30 as an example. The driving method includes the following steps: First, as shown in step 510, a scan driving signal S(2) is generated on the scan line 310(2) and output to the pixel 300. Next, as shown in step 520, a scan drive signal S(3) is generated on scan line 310(3), and _ to level shifting element 340 is output. As shown in the last step 530, the level conversion element 340 is enabled in accordance with the scan driving signal S(3) such that the voltage levels of the pixel electrode a and the pixel electrode b are different. As described above, the liquid crystal display of the present invention enables the switch Q3 by the next adjacent scan driving signal so that the pixel voltage Va of the sub-pixel 330(1) is slightly different from the pixel voltage Vb of the sub-pixel 330(2). Since the pixel voltages Va and Vb are different, the rotation angles of the liquid crystal molecules of the sub-pixel 330(1) and the sub-pixel 330(2) are made different. The problem of color shift caused when the user views the liquid crystal display panel 30 at different angles is improved. The liquid crystal display and the driving method thereof disclosed in the above embodiments of the present invention improve the color shift phenomenon of the image surface by slightly making the pixel voltages of the two sub-pixels in the same pixel slightly different, so as to improve the quality of the kneading surface. In view of the above, the present invention has been disclosed in a preferred embodiment, and is not intended to limit the present invention.
