Abstract: PROBLEM TO BE SOLVED: To improve the service life of a screen by making mutual separation of the surfaces of two sets of alternate parallel bands, at least within the energy range of the primary electrons and with an insulating band including such a material as having its secondary radiation factor less than one. SOLUTION: ITO band 9 of an anode 5' is separated by an insulating band 20 including the first insulating layer 8' made of silicone oxide, and the insulating layer 8' is coated with the very thin second layer of materials whose secondary radiation factor is less than one. In order to improve insulation between adjacent bands by providing spaces at both sides of layer 21, insulating space of the second layer 21 is made smaller in its width than that of the insulating layer 8'. Since the surface material 21 of the insulating band 20 has its secondary radiation factor less than one, the end of the surface material 21 is subjected to negative electric load so that its screen makes action when the primary electrons are passed form a micro-chip. This negative electric load increases up to its electric load balancing point by applying negative bias to a band adjacent to the luminous element. Accordingly, any of color shift phenomenon can be eliminated.

Abstract: The screen has a cathode composed of microdots (2) for electron bombardment of an anode (5) provided with luminophores (7) of the primary colours on strips (9) of indium-tin oxide deposited on the glass (6). The strips are separated by insulation (20) whose surface (21) has a secondary emission coefficient less than 1 at least within the range of primary electron energies. Each insulating strip of e.g. silicon dioxide has sufficient resistivity to prevent breakdown between two neighbouring luminophores. Its surface may have a coating of low-emission material (e.g. silicon) to a thickness of about 100 Angstrom with a gap of 5-10 mu m at each edge.
