PURPOSE: A display device is provided to prevent a current from flowing to a resistance if an PFC circuit is not operated. CONSTITUTION: A power supply unit(18) includes a power converting unit(130), a feedback unit(140), a power factor compensation unit(110) and an electric power reduction unit(150). The power converting unit outputs an operation voltage through conversion of a level of a DC voltage. A feedback unit outputs a feedback voltage about the DC voltage. The power factor compensation unit performs compensating a power factor of the power supply unit. The electric power reduction unit controls an output of the feedback unit.
