The invention relates to a display unit and driving method thereof. The range of the application voltage (low application voltage) higher than the maximal (minimal) application voltage of bygone maximal (minimal) liquid crystal transparency degree is set. A liquid crystal response correction unit (106) sets reference voltage to use the range for liquid crystal response correctinf. A gamma regulating unit (107) and a gray scale plugging unit (108) are mounted. The said gamma regulating unit and gray scale plugging unit adjust the deviation of gamma character reduced from extension of range ofapplication voltage.
