The invention discloses a driving method of a liquid crystal display device. The liquid crystal display device comprises a lower substrate, an upper substrate, and a liquid crystal layer positioned between the lower substrate and the upper substrate, wherein the upper substrate is provided with a first biased electrode and a second biased electrode; the first biased electrode comprises a pluralityof first electrode bars; odd rows of pixel units are respectively covered with the plurality of first electrode bars; the second biased electrode comprises a plurality of second electrode bars; evenrows of pixel units are respectively covered with the plurality of second electrode bars. According to the driving method, through an arrangement way of the biased voltages and a voltage driving way of the upper substrate (namely a colored-film substrate), together with a reverse rotation driving way of the lower substrate (namely an array substrate), switching between wide and narrow view modes is realized; under the premise of maintaining an existing peeping prevention effect, a penetration ratio under the narrow view mode can be increased, and the contrast degree under the narrow view modecan be greatly improved, and the display picture quality of the display device having switchable view angles is improved.
