Abstract:
An electron source comprising:a plurality of first conductors disposed at predetermined intervals on a substrate; a plurality of second conductors disposed at predetermined intervals on the substrate, wherein said second conductors intersect said first conductors so that said first and second conductors constitute a matrix conductor; a plurality of electron emitting devices disposed in a matrix on the substrate, wherein each of said electron emitting devices is connected to one of said first conductors and to one of said second conductors; a third conductor disposed along a direction in which said first conductors extend along the substrate, said third conductor positioned between said electron emitting devices which are outermost in the matrix and an outer periphery of the substrate, at a side opposite to a side where at least one of said first conductors connected to at least one outermost electron emitting device is disposed, wherein said third conductor is not connected to at least one of said electron emitting devices connected to said second conductors; and a fourth conductor disposed along a direction in which said second conductors extend along the substrate, said fourth conductor positioned between said electron emitting devices which are outermost in the matrix and an outer periphery of the substrate, at a side opposite to a side where at least one of said second conductors connected to at least one outermost electron emitting device is disposed, wherein said fourth conductor is not connected to at least one of said electron emitting devices connected to said first conductors.
