Image forming device

Abstract

Abstract PURPOSE:To obtain stable luminescence with no deterioration of the luminescence effect by providing atmospheric pressure-resistant spacers along the orbit of electrons emitted from surface conductive type electron emitting elements. CONSTITUTION:A thin film 3 made of an electron emitting material having a neck section is formed on a quartz substrate 4. Electrodes 1 and 2 having electric connection to electron emission sections 5 to be provided on the film 3 are formed. The electron emission sections 5 are formed between the electrode 1 and the electrode 2. A phosphor target 7 is arranged on spacers 11. When such spacers 11 are provided, the surface breakdown voltage is increased, the arriving current quantity to the target 7 has no loss, and luminescence with high efficiency and high brightness is obtained.
