PROBLEM TO BE SOLVED: To provide a display apparatus provided with a common electrode driving circuit, having a single-channel configuration capable of reducing the circuit scale. SOLUTION: The display apparatus is provided with a plurality of pixels and the common electrode drive circuit, which has a plurality of basic circuits. The basic circuit comprises a means 1 of latching a first input signal at timing when a clock signal is changed from a second voltage level to a first voltage level; a means 2 of latching a second input signal at timing, when the clock signal is changed from the second voltage level to the first voltage level; a first switching means allowed to be switched, on the basis of the voltage latched by the means 1 and to output first power supply voltage to an output terminal in an ON-state; and a second switching means allowed to be switched, on the basis of the voltage latched by the means 2 and output second power supply voltage to the output terminal in the ON-state. The first or the second input signal is changed from the first voltage level to the second voltage level, after changing the clock signal from the first voltage level to the second voltage level.
