ELECTRON SOURCE AND IMAGE FORMING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To attain prevention of electromagnetic wave radiation, with an elec tron source with a plurality of electron-emitting elements in a matrix of a plurality of row and column circuits arranged on a substrate. SOLUTION: With an electron source 1 with a plurality of electron-emitting elements arranged in matrix in a plurality of row circuits and column circuits on a substrate 101, a conductive layer 19 insulated from the row and column circuits is arranged at least at a corresponding part of the matrix in the substrate 101.
