Abstract
In a liquid-crystal display panel drive power supply circuit that has a first power supply of a high potential, a second powers supply of a potential that is lower than that of the first power supply, a plurality of resistors that are provided in series between the first and second power supplies, and a plurality of voltage-follower configured amplifiers for the purpose of introducing mutually different voltages present at the connection points between the resistors to a liquid-crystal panel, capacitors are inserted between the output terminals of the amplifiers and the second power supply.
