Abstract
According to the color cathode ray tube of the present invention, a magnetic resistance section is provided between a shadow mask and a mask frame. The magnetic resistance section comprises at least one of magnetic resistance members and a gap which is provided between the shadow mask and the mask frame. The magnetic resistance section serves to reduce a landing error of electron beams on a phosphor screen.
