Abstract of the Disclosure Color Picture Tube The novel type of color picture tube comprises electron guns (7 to 12) disposed in the corners of a triangle, a slit-type shadow mask (3) and a phosphor screen (2) con- sisting of vertical phosphor stripes. In the electron-gun system and/or on the side thereof facing the deflection unit (6), or between the electron gun system and the de- flection unit (6),there is provided an additional magnetic deflector (15; 16). This deflector serves to deflect the electron beams (13) in such a way that they, within the range of action of the deflection unit (6), extend in a horizontal common plane passing through the tube axis (14).
