ABSTRACT:
The present invention is concerned with an electron beam apparatus comprising: a hermetic container; an electron source disposed within the hermetic container; and a spacer; wherein the spacer includes at least a region where a layer containing fine particles exists, a sheet resistance measured at the surface of the region of the spacer is 107Ω/□ or more, and the fine particles are 1000 Å or less in the average diameter of the particles and includes at least metal elements. The electron beam apparatus exhibits the excellent display quality which suppresses the displacement of the light emission point with the charge and the creeping discharge, and the long-period reliability.
