An electric power circuit for driving a display panel, which supplies a plurality of gradation voltages to driver parts of the display panel, is provided. The electric power circuit has a fine-controlling circuit for fine-controlling the gradation voltage in response to a difference between the gradation voltage and a referential voltage, by which excess increase and decrease of the gradation voltage can be appropriately suppressed. Therefore, the electric power circuit can generates a stable gradation voltage.
