Patent ID: 7414602

Claim:
A method of driving a liquid crystal display device, the device comprising a pair of substrates with a liquid crystal layer interposed therebetween, one substrate of the pair of substrates being an active matrix substrate on which a plurality of pixel switching elements, a plurality of scanning lines connected to the plurality of pixel switching elements, and pixel electrodes connected to the plurality of pixel switching elements are provided, and the other substrate of the pair of substrates being an opposing substrate provided with a common electrode on at least a part of a surface contacting the liquid crystal layer, and a scanning line driving circuit being connected to a plurality of scanning lines and sequentially outputting at different timings for every scanning line one or plural selection potentials for making the pixel switching elements connected to the plurality of scanning lines in a low impedance state and one or plural non-selection potentials for making the pixel switching elements connected to the corresponding scanning lines in a high impedance state, and the scanning line driving circuit being connected to a plurality of power source lines of different potentials, wherein the method is a common inversion driving method for alternately inverting a common high state in which the common electrode has a relatively high potential and a common low state in which the common electrode has a relatively low potential, and a common inversion operation in which the potential of the common electrode is changed from the common high state to the common low state and from the common low state to the common high state is implemented in a floating state in which at least a part of the plurality of scanning lines, more preferably, all of the scanning lines or all of the scanning lines except one scanning line are electrically isolated from all of the plurality of power source lines by a relatively high electrical resistance.
