    • An objective of the present invention is to provide a power supply device, a liquid crystal display device, and a method of supplying power that can enable designs with lower power consumptions and can also enable higher display qualities. A first voltage Vx, which is a constant voltage, is generated by a first voltage generation portion in a voltage regulation portion. A second voltage Vy having a value independent of that of Vx is generated by a second voltage generation portion, and Vx and Vy are added by an adder portion to generate a regulated voltage Vreg. A control portion provides variable control of Vy within a voltage regulation range that is defined to include Vx. The regulated voltage Vreg is divided by a voltage divider portion within a multi-value voltage generation portion. The impedances of voltages V2 and V4 are converted by first impedance conversion portions (n-type OP-amps), and the impedances of voltages V1 and V3 are converted by second impedance conversion portions (p-type OP-amps).
