Abstract
Electron source with micropoint emissive cathodes and display means by cathodoluminescence excited by field emission and using said source. Each cathode (5) comprises an electrically conductive layer (22) and micropoints (12) and, according to the invention, a continuous resistive layer (24) is provided between the conductive layer and the micropoints. The display means comprises a cathodoluminescent anode (16) facing the source.
