Image forming apparatus and a method for manufacturing the same

An electron source comprising:

• (a) a substrate;
• (b) plurality of electron emitters arranged on said substrate, said electron emitters comprising first and second electrodes;
• (c) plural first wirings arranged on said substrate substantially aligned in one direction and connected to said first electrodes;
• and
• (d) plural second wirings aligned substantially perpendicular to the first wirings and connected to said second electrodes, said second wirings overlying said first wirings and defining intersections between said first and second wirings with an electrically insulating layer disposed between said first and second wirings at said intersections;
• wherein said first wirings cover a portion of said first electrodes, said second wirings cover a portion of said second electrodes, and said first electrodes are longer than said second electrodes in the longitudinal direction of said second wirings, and
• wherein said first and second electrodes oppose each other, and a direction in which said first and second electrodes are oppposed to each other is substantially parallel to the alignment direction of said second wirings.
