Abstract: A liquid crystal display device is manufactured at a low cost. In the liquid crystal display device, three sub-pixel electrodes are connected by inter-electrode connection portions to form one pixel electrode. One TFT is connected to the pixel electrode. A screen of a liquid crystal display panel is divided into n (n≥2) of areas. Gate signal lines G of each divided area are scanned simultaneously one line at a time in each divided area. A backlight device emits light after completion of the scanning of each divided area.
