Abstract: A method of driving a liquid crystal display panel is provided. The liquid crystal display panel includes: a liquid crystal display pixel including a liquid crystal structure including a pixel electrode, a liquid crystal layer, and a common electrode; a switching transistor connected between the pixel electrode of the liquid crystal structure and a data-line; and a storage capacitor connected to the pixel electrode of the liquid crystal structure. The method includes: calculating an accumulated driving time of the liquid crystal display panel by accumulating a driving time of the liquid crystal display panel; determining whether or not the accumulated driving time has reached a deterioration reference time; and when the accumulated driving time is determined to have reached the deterioration reference time, changing a gate-off voltage applied to a gate terminal of the switching transistor and a common voltage applied to the common electrode.
