To provide a cathode-ray tube device correcting asymmetric focus deterioration caused by center dislocation of an electron gun even after the electron gun is incorporated.

The cathode-ray tube device has the electron gun incorporated in the inside of a neck part and a deflecting yoke mounted on the outer circumference of a funnel part, and a pair of correction coils arranged in the outer circumference of the neck part so as to face in the same direction as a direction in which a pair of vertical deflection coils in the deflection yoke is faced, and the pair of correction coil generates a magnetic field displacing electron beams flowing through the electron gun by supply of DC current in the vertical direction.
