Claims

[Scope of utility model registration request]

A color picture tube device comprising: an in-line electron gun that emits a central electron beam and both side electron beams; a display surface provided opposite to the in-line electron gun; and an external magnetic deflection yoke. A plurality of magnetic bodies for matching the convergence of the central electron beam and the electron beams on the display surface on the display surface are arranged at least perpendicularly to the path of the central electron beam within the range of the leakage magnetic field of the external magnetic deflection yoke. A color picture tube device characterized in that the color picture tube device is arranged in a distributed manner on two planes or on at least two curved surfaces substantially along a plane of equal magnetic force of the leakage magnetic field.
