The present disclosure relates to a power circuit and a display device including the same. The power circuit includes an output terminal configured to supply an output voltage to a digital circuit; a current sensing resistor connected to the output terminal; a sensing part configured to receive a first reference voltage and voltages of both ends of the current sensing resistor and vary one of a feedback voltage and a second reference voltage; and a voltage generation part configured to receive the feedback voltage and the second reference voltage and lowers the output voltage when a current flowing through the current sensing resistor decreases.
