The present invention relates to a power supply circuit of a display device, capable of preventing an abnormal display by masking an output of a timing controller in a section where a power supply is unstable so as to block an output of a level shifter, and to a method for driving the same. The power supply circuit of the display device comprises: a voltage generation unit for generating and outputting a plurality of driving voltages by using an input voltage; a control logic for generating and outputting a gate control signal which controls a drive timing of a gate driver by using a timing signal inputted from a timing controller; a level shifting unit for shifting a level of the timing signal from the timing controller and the gate control signal from the control logic and outputting the level-shifted signals to the gate driver; and a masking logic unit for blocking an output of the level shifting unit in a section where the driving voltage is stable by using an input masking signal and the timing signal inputted from the timing controller. |
