The present invention provides a polarity inversion driving method for a liquid crystal display panel. The polarity inversion driving method comprises a step of performing polarity inversion on groups of pixel units according to a preset period, wherein each group of pixel units comprises rows of pixel units sequentially arranged in a same column, and a gate on-state duration of the first row of pixel unit in each group of pixel units is longer than the gate on-state duration of the remaining rows of pixel units in the group of pixel units. Correspondingly, the present invention further provides a polarity inversion driving device for a liquid crystal display panel. According to the present invention, when N-dot inversion driving is performed on the liquid crystal panel, charging times of respective rows of pixel units in each group of pixel units are closer.
