ABSTRACT:
A cathode ray tube having a deflection unit, the play between the deflection unit (11) and the envelope (4) being different for two perpendicular (x and y) directions. This enables the tilt of the deflection unit relative to the envelope to be greater in a direction than in a direction at right angles to said direction. By virtue thereof, the distance between the deflection unit and the electron beams can be reduced, so that the deflection requires less energy and can be improved.
