Claim:
1. A mobile terminal comprising: a display panel provided with a source line and a gate line; a power storage device; a power circuit section configured to generate a first logic power supply voltage and an analog power supply voltage higher than said first logic power supply voltage, both the first logic power supply voltage and the analog power supply voltage generated from a power received from said power storage device, to provide said first logic power supply voltage to a first power supply line and to provide said analog power supply voltage to a second power supply line; a gate line driving section configured to drive said gate line; a source line driving section configured to drive said source line; a first regulator provided with an input for receiving said first logic power supply voltage and configured to step said first logic power supply voltage down to generate a second logic power supply voltage, and provide said second logic power supply voltage to a third power supply line; a logic circuit configured to receive said second logic power supply voltage from said third power supply line and control said gate line driving section and said source line driving section; and a charge transport path, wherein said logic circuit is configured to control said gate line driving section and said source line driving section in response to a decrease of at least one of a voltage of said first power supply line and a voltage of said second power supply line, so as to discharge a charge stored in said display panel, and wherein said charge transport path is configured to transport a charge from said second power supply line to said third power supply line in response to a decrease of voltage of said first power supply line.
