PROBLEM TO BE SOLVED: To solve the problems that a matrix type liquid crystal display device has required a new circuit board design such as arrangement of storage capacitor and wiring thereto to suppress power consumption, and also the number of parts has had to be increased. SOLUTION: In the liquid crystal display device, a column electrode and a counter electrode are provided with a switch for temporarily shorting both electrodes in synchronizm with the timing of alternating. Thus, voltage can be changed almost to the middle of the alternating without consuming power, and it is also unnecessary to arrange new external components. Therefore, low power consumption and cost reduction can be achieved. |
