PROBLEM TO BE SOLVED: To obtain the CRT display device that is provided with an image pattern tilt correction means. SOLUTION: A horizontal sawtooth wave circuit 4 generates a horizontal sawtooth wave synchronously with a received horizontal synchronizing signal H and a sawtooth wave modulation circuit 5 generates a modulated horizontal sawtooth wave based on the horizontal sawtooth wave. Then a vertical deflection current circuit 7 superimposes a modulated horizontal sawtooth wave on a vertical deflection current generated by a vertical output circuit 6 and the result is fed to a vertical deflection coil 8, which corrects a vertical inclination of an image. Thus, a modulation amount of a horizontal modulation circuit 21 is controlled by a control signal 1 to correct a horizontal tilt of the image. |
