ABSTRACT:
In a color cathode ray tube apparatus of this invention, if an outer diameter of a neck having a cylindrical shape is represented by D.sub.N and an interval of adjacent electron beams at a screen-side end portion of an electron gun is represented by Sg, a value D.sub.N /Sg is 8.0 or more. A deflection means has a saddle-type horizontal deflection coil for deflecting electron beams in an in-line direction. If the length of the deflection means in a direction of the tube axis is represented by l.sub.H all, l.sub.H all is 90 mm or more.
