Abstract: PROBLEM TO BE SOLVED: To improve a displayed image brightness even if amplitude modulation is operated by shading correction, by arithmetically processing amplitude attenuation for canceling an increase in a peak of an amplitude caused by an amplitude modulation correction also in an after-stage circuit in which an amplitude modulation was carried out by shading correction. SOLUTION: A shading correction wave is outputted from a correction wave generation circuit 6, and is amplitude-adjusted by a voltage control amplifier 7. Also, the shading correction wave is outputted from a shading output circuit 3 to a multiplier 1, and a video signal is amplitude-modulated by the multiplier 1. The amplitude-modulated video signal is inputted to a voltage control amplifier 5. The video signal is corrected by an arithmetically processed voltage Vg by inputting an amplitude correction data β outputted from an amplitude control circuit 4.  When no shading correction is done, the amplitude correction data β outputted from the amplitude control circuit 4 is made to zero (0), and when shading correction is operated, the video signal amplitude of the voltage control amplifier 5 is attenuated equivalently to that for the case without modulation for shading correction.
