  • Patent number: 5519282
    Abstract: 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) has a triple coat layer formed on a face plate thereof. The triple coat layer includes a high-refractive transparent conductive layer, a low-refractive smooth transparent layer, and a low-refractive rough transparent layer; and is formed on the face plate 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.
