ABSTRACT:
A method for driving a display device including a display medium; a pair of substrates opposed to each other and interposing the display medium therebetween; a common electrode provided on one of the pair of substrates; and a switching element, a scanning electrode for applying a voltage for controlling the switching element to be in one of an ON state and an OFF state, and a signal electrode for applying a voltage in accordance with image data to the display medium, all of which are provided on the other substrate of the pair of substrates. The method includes the steps of driving the common electrode by a voltage represented by a first function which indicates a waveform of a voltage for driving the common electrode and uses time as a variable; and driving the scanning electrode by a voltage represented by a second function which indicates a waveform of a voltage for driving the scanning electrode and uses time as a variable, in the state where a primary differential of the first function and a primary differential of the second function are equal to each other when the switching element is in the OFF state
