Abstract

PURPOSE:To elevate luminous brightness by using a luminous body made by zinc oxide porcelain and zinc sulfide magnetic luminous layer as a luminous screen. CONSTITUTION:A luminous screen and a electron gun are held in a vacuum vessel 5. A luminous screen is structured by a luminous body formed in zinc oxide porcelain 1, the surface of which is a zinc sulfide magnetic luminous layer 2 and an aluminium film 3. Because of this, it can be achieved to make a luminous reflection conductive film, i.e., an aluminium film 3 thin and to greatly improve luminous brightness at a low accelerating voltage.
