In a thin film transistor liquid crystal display (TFT-LCD), a connection is formed between the gate line and the common electrode line with TFTs. During scanning in one frame, a high voltage signal is applied to the pixels in a next row before the next row is turned on, i.e., a black image is inserted in the normal white mode. When the pixels in one row are in operation and the pixels in the next row are not turned on, a black image data is inserted into the next row. A high voltage is applied before the pixels in a row of the TFT-LCD are turned on, so that a black image is inserted and tailing of motion picture can be alleviated.
