Abstract
To easily reduce the occurrence of uneven luminance or flicker in a screen without any manufacturing or cost problems. An output potential waveform outputted from a switching unit 16 of a gate driver IC 7 to a scanning line G is set to have a first waveform having a potential for turning on a switching elements set as its amplitude, and a second waveform connected to the first waveform and oscillated within a period shorter than the second waveform with amplitude smaller than that of the first waveform. Thus, a falling waveform of a scanning signal to be supplied to the switching elements through the scanning line G is inclined beforehand, nonuniformity of the inclination of the falling waveform of the scanning signal supplied to each of the switching elements is reduced, and the occurrence of uneven luminance or flicker in the screen is suppressed.
