PROBLEM TO BE SOLVED: To easily decrease occurrence of brightness unevenness and flickering without problems in productivity and costs. SOLUTION: An output waveform of a potential outputted from a switching part 16 of a gate driver IC 7 to scanning lines G is set as a waveform including a 1st waveform which has a potential to bring a switching element into ON state as the amplitude, and a 2nd waveform which follows the 1st waveform, and also oscillates within a period shorter than the 1st waveform with an amplitude smaller than the 1st waveform. Thus, the falling waveforms of the scanning signals to be supplied to the switching elements via the scanning lines G are made to beforehand decline, to relax the unevenness of the declinations of the falling waveforms of the scanning signals to be supplied to each switching element, and thereby suppress occurrence of brightness unevenness and flickering in a screen.
