Abstract
By a simple circuit configuration, luminance unevenness is suppressed, and charge remaining after a power source supply is interrupted is suppressed. A slope control unit () generates a switch control signal (Von) having a waveform with a falling slope, by switching between a grounded state of being connected to a ground and an ungrounded state, and modulating the waveform of a high voltage (VGH), and in a case where a power supply from the outside is interrupted, the slope control unit () is in the ungrounded state.
