Zusammenfassung:	A signal processing circuit (100) is provided with: a signal separation unit (110) configured to separate an input video signal into components of individual colors; an expanded video signal generation unit (130) configured to perform an expansion process for increasing a signal value of the input video signal, and output data obtained by the expansion process as an expanded video signal; an expansion coefficient decision unit (120) configured to decide an expansion coefficient E to be used for the expansion process; and an output video signal generation unit (140) configured to generate an output video signal to be outputted to the display panel based on the expanded video signal. The expansion coefficient decision unit (120) decides an inverse of saturation, obtained based on the input video signal, as the expansion coefficient E for each pixel.
