The invention provides a liquid crystal display panel and a driving method thereof, the method includes: providing a liquid crystal display panel, which includes a pixel matrix of M×N, every pixel consists of a red sub-pixel, a green sub-pixel and a blue sub-pixel in sequence, making the LCD panel include a sub-pixel matrix of M×3N, aiming at the sub-pixel matrix, a dividing operation is executed, a first sub-pixel in the sub-pixel couple of each color is provided with a higher gray-scale value BH, a second sub-pixel in the sub-pixel couple of each color is provided with a lower gray-scale value BL, making a brightness curve of each sub-pixel at an angle of side view approach a scheduled Gamma curve. The liquid crystal display panel and the driving method thereof can reduce the color shift of the liquid crystal display panel when viewed at an angle of side view.
