Summary:Provided is a liquid crystal display device and its driving method, which can simplify the hardware structure of the liquid crystal display device driven by a pulse driving method and minimize the capacity of a memory for storing the data. The liquid crystal display device comprises a liquid crystal display panel, a sequential controller, a data drive circuit and a first and second grid drive IC.The sequential controller generates the grid sequential control signal and the data sequential control signal. The data drive circuit supplies the positive polarity/negative polarity analog video data and the positive polarity/negative polarity black voltage for a data line. The first grid drive IC shifts the first grid starting pulse and supplies the first grid pulse in sequence in the low logicperiod of the first grid output enable signal for the grid lines contained in the first block of the liquid crystal display panel. The second grid drive IC shifts the first bearing signal supplied from the first grid drive IC
