Abstract
Uniformity of the electron emission characteristics of electron emitting devices is improved. A substrate is formed with row-directional wires and column-directional wires electrically connected to electron emitting devices disposed in a matrix shape and each having electrodes and an electroconductive film. A pseudo row-directional wire is formed at a position X0 between a position X1 of a row-directional wire and a periphery of the substrate, and a pseudo column-directional wire is formed at a position Y0 between a position Y1 of a column-directional wire and a periphery of the substrate. Pseudo electrodes and are electrically connected to the pseudo row-directional wire and pseudo column-directional wire.
