Abstract
A method of driving a liquid crystal display and the liquid crystal display of the present invention are such that in a liquid crystal display in which video signals are written onto a plurality of pixels frame by frame (Tf), voltages corresponding to the video signals are held in the pixels, and a modulation degree of the liquid crystal layer in an alignment state for display is controlled in accordance with the held voltages, thereby displaying an image, a backward-transition-prevention voltage ΔV for preventing backward transition of a liquid crystal layer is temporalily superposed on the voltages (Vd–Vdn) corresponding to the video signals in a hold period (Th) of the voltages (Vd–Vdn) corresponding to the video signals.
