A display panel for driving a display panel in response to data and gate signals, includes first and second switching sections, a timing control section, a driving voltage generating section, a gate driving section and data driving section. The first switching section switches a source voltage in response to a first switching signal. The timing control section outputs a gate control signal and a data control signal in response to the source voltage. The driving voltage generating section receives the source voltage to output first, second and third driving voltages. The second switching section switches the first, second and third driving voltages. The gate driving section outputs the gate signals in response to the first and second driving voltages. The data driving section outputs the data signals in response to the third driving voltage. The display panel eliminates a noise generated when an electric power is off.
