Summary:PURPOSE:To obtain a liquid crystal display device capable of displaying gradation with a simple driving power source. CONSTITUTION:This liquid crystal display device has a liquid crystal cell 1 holding a crystal layer 6 between two sheets of substrates 3 and 5 in which plural pixel electrodes 4 are formed in one side and a driving power source 18 impressing voltages to electrodes 4. Each pixel electrode 4 of the liquid crystal cell is composed of plural divided electrodes 41 to 45 having different dimensions and divided electrode parts are driven independently by the driving power source 18.
