The present invention relates to a power supply circuit of a display device to simplify the configuration of a level shift which generates driving voltages required for alternate driving. The power supply circuit comprises an alternate driving control signal generation part which generates an alternate driving signal for the alternate driving based on a simple timing signal, and an alternate driving voltage generation part which switches a first driving voltage and a second driving voltage according to the alternate driving control signal between an on-level and an off-level, and switches the first driving voltage and the second driving voltage in opposite directions. The simple timing signal includes at least one among a gate start signal, an on clock, and an off clock. |
