Abstract: A panel of a metal backed color cathode ray tube and a manufacturing method thereof are disclosed which are characterized in that the height of the graphite remaining on the skirt is higher than or same as the metal deposition height of the deposited metal layer, and that a shielding plate having a height higher than or same as the cutting height of the graphite is used on a deposition dolly for forming the deposited metal layer. According to the present invention, the deposited metal layer is neither floated nor detached due to the combustion of the organic materials used in forming the luminescent layer or the intermediate layers such as the filming layer, and therefore, the defect rate due to the blocking of the holes of the shadow mask is markedly reduced, thereby making it possible to save labor and materials in producing the product, and concomitantly upgrading the quality of the metal backed color cathode ray tube.
