摘要： A display panel driving circuit for driving a display panel, in which the electric power consumption at the time of the switching can be reduced. The display panel driving apparatus allows the use of a switching device of a low withstanding voltage. A transition voltage generating circuit for shifting a voltage of a DC power source of the driving apparatus is provided. A resonance relay circuit is provided for generating a pulse having a leading edge which rises gradually and a trailing edge which decreases gradually based on the transition voltage and supplying it as a drive pulse to the display panel. A plurality of resonance circuits for driving and exciting capacitive devices of the display panel are provided in a range of different driving potentials. The drive pulse having the leading edge which rises gradually and the trailing edge which decreases gradually is generated by switching each of the resonance circuits by the switching device to make them operative sequentially.
