1. A driving method of a liquid crystal display device comprising a liquid crystal element, the driving method comprising:

  • supplying data of an image signal to the liquid crystal element in a first frame period;

    stopping supply of the data in second to n-th frame periods, wherein n is a natural number larger than 1;

    inverting a polarity of a voltage, which is applied to the liquid crystal element, between the n-th frame period and a (n+1)-th frame period; and

    compensating the voltage when an absolute value of the voltage in the n-th frame period is different from an absolute value of the voltage in the (n+1)-th frame period, so that the absolute value of the voltage in the n-th frame period is the same as the absolute value of the voltage in the (n+1)-th frame period,wherein the liquid crystal element is electrically connected to a transistor which comprises an oxide semiconductor in a channel formation region, andwherein a still image is formed in the first to (n+1)th frame periods.
