A driving method of liquid crystal panel includes: providing a liquid crystal panel including multiple pixel units, each pixel unit at least including a blue sub-pixel; dividing the liquid crystal panel into multiple display units, each display unit including neighboring first pixel unit and second pixel unit; and for a grayscale value B of blue sub-pixel required by the display unit, providing the blue sub-pixel of the first pixel unit with a grayscale value BH and providing the blue sub-pixel of the second pixel unit with a grayscale value BL, and the combination of the grayscale values BH and BL making a brightness of the blue sub-pixels of the display unit at an oblique viewing angle be approximate to a predetermined Gamma(γ) curve. γ=1.8˜2.4. Moreover, a liquid crystal panel being driven by the above driving method also is provided.
