A colour display device comprising a cathode ray tube and a deflection unit. The display device includes compensation magnets for correcting a raster distortion in the raster displayed on the screen. Said magnets (25, 26) comprise a shunt (25a, 26a) to increase the temperature coefficient of the permanent remanence. Preferably overcompensation occurs, i.e. the temperature coefficient is changed from a negative to a positive value. |
