１に選定することを特徴とする陰極線管。 A face panel with a phosphor film and a metal back layer formed on the inner surface is sealed with a funnel having a graphite film formed on the inner surface of the flare part with a frit interposed.
In the case where the lead is led out by penetrating the frit sealing part, a non-conductive part is left between the metal back layer and the graphite film within a creepage distance l, and the creepage distance is lmm.
A cathode ray tube characterized in that the ratio l/V of the high applied voltage VKV for operation is selected to be approximately 1.
