Zusammenfassung:	Picture display device having a display tube and a deflection unit (9) comprising a field deflection coil and a line deflection coil (11). In order to comply with a predetermined interference radiation standard, the picture display device is provided with a compensation coil system having a first set of compensation coils (18, 19) for generating a dipole compensation field and possible a second set of compensation coils (18a, 19a) for generating a fourpole compensation field, the compensation coil system being preferably arranged in series with the line deflection coil 11 and being provided with electric means (R; R1; R2; R3; R4) to shift the phase of the current through at least a part of the compensation coil system with respect to the phase of the current through the line deflection coil.
