Abstract
An anode of a field emission display has a substrate, a conductive layer, and one or more conductive members kept at a potential higher than the conductive layer to increase the component of the electric field normal to the surface of the anode at corners and edges of the anode so that the brightness across the display is more uniform than it would be without the conductive members.
