Abstract
Disclosed is a method for driving an active matrix type liquid crystal display device including a first electrode, a second electrode, and a liquid crystal layer interposed between the first and the second electrodes, and the liquid crystal layer having a larger polarization when a voltage of a first polarity is applied to the first electrode against the second electrode than that when a voltage of a second polarity different from the first polarity is applied to the first electrode against the second electrode, the method comprising dividing a frame into a first field and a second field, applying a first voltage of the first polarity to the first electrode during the first field, generating a second voltage from the first voltage by changing its polarity, a magnitude of the second voltage being modified by an amount of ΔV (ΔV≠0) based on a magnitude of the first voltage in a direction of the first polarity when the first voltage is not zero, and applying the second voltage to the first electrode during the second field.
