置。[Claims for Utility Model Registration] A color display device that displays image information by being supplied with a composite video signal and an RGB signal, wherein a horizontal phase adjustment circuit that generates a horizontal drive signal from a horizontal synchronization signal includes the composite video signal and the RGB signal. The phase of the horizontal drive signal generated from the first horizontal synchronization signal in the video signal is adjusted relative to the first horizontal synchronization signal by a delay circuit provided in the luminance signal amplification stage in the composite video signal. and a correction circuit that advances the phase of the horizontal drive signal generated from the second horizontal synchronization signal in the RGB signal with respect to the second horizontal synchronization signal by the amount of the delay circuit. A color display device characterized by being provided with one of the correction circuits.
