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 ( 25 a, 26 a) 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.
