摘要： In a unit drive circuit in each stage in a shift register, a transistor which is maintained in ON state during a period where the unit drive circuit in the stage does not perform an outputting operation is configured not to generate Vth shift. As switches, transistors T6A, T6B are connected between the output terminal OUT and AC power sources VA, VB. At least one of T6A, T6B is brought into ON state and T6A, T6B are alternately brought into OFF state during the period other than the outputting operation period. VA, VB supply L level during a period where T6A, T6B are in ON state, while VA, VB supply a ground potential GND which is an intermediate potential between an H level and an L level during a period where T6A, T6B are in OFF state.

摘要： Provided are a power supply circuit and a display device which are capable of enhancing power efficiency even when applied to a display panel whose current consumption varies. The power supply circuit boosts and outputs an input voltage using a booster chopper circuit. A frequency control circuit changes a frequency of a clock signal, which controls a switch of the chopper circuit, in accordance with a load of the power supply circuit. The frequency control circuit divides an operation of the display device into a display effective period at a high load and a vertical retrace period at a low load, based on a vertical synchronizing signal and a horizontal synchronizing signal. The frequency control circuit sets the frequency of the clock signal in a high-load period to be higher than that in a low-load period.
