Abstract
A color display tube is presented having an elongated display screen with a pattern of phosphor dots. In order to render mislanding errors of the electron beams as small as possible, particularly in the y direction, the color display tube has an internal shield which is provided proximate to its gun-sided open end with a structure for deflecting the field lines of the axial component of the earth's magnetic field more to the short sides than to the long sides of the shield. This structure is particularly constituted in that the short sides are provided with edges extending toward the gun, or in that a border strip has been removed from the long sides.
