Abstract

An image-forming device having, in an envelope, an electron-emitting element (5), an image-forming member (8) for forming an image by irradiation of an electron beam emitted from the electron-emitting element (5), and an electroconductive supporting member (10) for supporting the envelope (internally), comprises a means for controlling the potential (13) of the supporting member (10) to be not higher than the maximum potential applied to the electron-emitting element (5). The electron-emitting element (5) and the image-forming member (8) can be placed in juxtaposition on the same substrate (1), an electroconductive substrate (6) can be additionally provided in opposition to the face of the substrate, and the supporting member (10) can be connected electrically to one of said electrodes (2,3) and also to the electroconductive substrate (1). <IMAGE>
