Therefore, for the situation that above-mentioned same polarity and reversed polarity alternately occur, level is each other driven high by B sub-pixel during same polarity and G sub-pixel, B sub-pixel and G sub-pixel is made to present partially black state, level is each other dragged down by B sub-pixel during reversed polarity and G sub-pixel, B sub-pixel and G sub-pixel is made to present partially white state, by partially black state and the partially white state of above-mentioned alternately appearance, compensate each other from aberration, the voltage disturbance between the sub-pixel of reduction close together.Thus then there will not be the phenomenon of colour cast from the Macrovision angle of overall display panels, reduce the defects of vision of whole liquid crystal display, even make whole liquid crystal display there are not the defects of vision.
