The purpose of the present invention is to suppress brightness variations and suppress charge remaining after interrupted power supply by a simple circuit constitution. A slope control unit (52) switches between a grounded state connected to a ground and a non-grounded state so as to modulate a high-voltage (VGH) waveform, thereby generating a switch control signal (Von) having a waveform fall slope, and when electric power supply from the outside is interrupted, the slope control unit (52) goes to the non-grounded state. |
