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 spacer 3 is set along a row-directional wiring 5 connected to a plurality of electron emitting devices 8 of a first substrate and a resistance film 14 formed on the surface of the spacer 3 is brought into contact with and electrically connected to a conductive member 11 such as a metal backing on a second substrate 2 and the row-directional wiring 5 on the first substrate while the shape of the contact face between the resistance film 14 and the row-directional wiring 5 or the resistance film 14 and the conductive member 11 has a concave shape or convex shape to be almost symmetric with respect to the center line of the spacer 3.
