Abstract
In a liquid crystal display device in which picture elements are arranged in a matrix form, a fixed time before a display data voltage is supplied to the picture element by a data line and a scan line, a pre-write voltage at a gradation value having a high speed of response to a change in gradation is supplied to the picture element regardless of the gradation value of a picture after response. When the display data voltage is supplied to the picture element, the pre-write voltage is always supplied to the picture element to thereby increase the response speed of liquid crystal constituting the liquid crystal display device regardless of the gradation value of a picture after response, so as to display quickly a picture on a display section.
