Abstract
A cathode includes microtips for flat display screens, of the type including cathode conductors, between a substrate and a gate, the gate including holes inside meshes defined by the cathode conductors. An insulating layer, including wells facing the holes, is interposed between the cathode conductors and the gate. Microtips are deposited in the wells, onto a resistive layer. The cathode conductors are deposited over the resistive layer and are coated with an auxiliary insulating layer.
