The present invention provides an image processing method of a hold type display device, a driving method of the display device and a display device driven by the method, for improving the moving picture quality without lowering the luminance and the contrast. In the image processing method for dividing one frame into sub frames, luminance components of a certain sub frame are distributed to other sub frames, so as to generate sub frame with luminance components higher than the average in the one frame and sub frame with luminance components lower than the average in the one frame, as a result of which the amount of luminance during one frame period is kept constant before and after the distribution of luminance components.
