A color cathode ray tube is disclosed, in which a purity correction means is installed in an outer side between an effective region and an effective screen, thereby decreasing distortion of the screen without deteriorating characteristics of a deflection yoke, and minimizing change of a misconvergence to improve color purity of the screen and productivity. To this end, the color cathode ray tube includes a panel (10) constituting a screen; a funnel (20) attached at the rear of the panel, having a bulb shape; a shadow mask (30) installed to be separated from the panel for choosing colors; and a purity correction means (60) installed to be close to the shadow mask. More preferably, the purity correction means (60) is attached in a range from a margin (S) of an effective screen of a panel to an effective end of the shadow mask (30) in an entire surface of the panel in which distortion of the screen is generated. |
