Abstract
A display tube has an electromagnetic deflection unit with line deflection coils of the semi-saddle type which are provided at their gun-sided ends with an extension having one single, wedge-shaped window directed towards the gun. Particularly line coma errors and raster errors, which occur in display tubes having display screens of small curvature and/or in the case of extreme long axis: short axis ratios, can be minimized with such line deflection coils.
