Abstract
To prevent an irregular shift of an electron beam emitted from an adjacent electron emitting device when preventing electrification of a spacer covered with a resistance film by using the spacer. A spaceris set along a row-directional wiringconnected to a plurality of electron emitting devicesof a first substrate and a resistance filmformed on the surface of the spaceris brought into contact with and electrically connected to a conductive membersuch as a metal backing on a second substrateand the row-directional wiringon the first substrate while the shape of the contact face between the resistance filmand the row-directional wiringor the resistance filmand the conductive memberhas a concave shape or convex shape to be almost symmetric with respect to the center line of the spacer
