ABSTRACT:
A method of producing a cathode-ray tube (CRT) of anti-static-processed type and further a cathode-ray tube which screens a leakage electric field (VLF band width). The method including the steps of forming a high-refractive transparent conductive layer, a low-refractive smooth transparent layer, and a low-refractive rough transparent layer on a faceplate of the CRT. This triple coat layer serving to reduce the weight of the CRT, minimize the deterioration of the resolution and contrast of images displayed, diminish the reflection of external light, and provide sufficient film strength for practical use.
