A liquid crystal television receiver includes a DC power supply to generate and output tuning DC power, a receiving portion, a display portion, and a series regulator. Preferably, the receiving portion is fed the tuning DC power and receives a video signal, the display portion includes an active-matrix liquid crystal panel, a gate driver to generate a gate-on signal and drive a gate line and a data driver to drive a data line, allowable ranges of voltage of the tuning DC power and the gate-on DC power share a common range in which a voltage of the tuning DC power is set, the tuning DC power is fed to the gate driver, and the series regulator is provided on at least one of power supply paths to feed the tuning DC power from the DC power supply to the gate driver and to the receiving portion, and removes noise component.
