Abstract:
An electron beam apparatus comprising:a first substrate that includes a plurality of electron-emitting devices, wherein said plurality of electron-emitting devices are provided in a vacuum container, a second substrate that is located opposite said first substrate and that has a region irradiated by electrons emitted by said electron-emitting devices in said vacuum container; at least one spacer that is mounted as an atmospheric-pressure resistant structure, that is sandwiched directly between said first and second substrates, or indirectly via an intermediate member between said first and second substrates, and that is extended longitudinally in a direction perpendicular to a direction in which said first and second substrates are positioned opposite each other; and a support member, for supporting said spacer outside an electro-emitting region that is defined between a region of said first substrate wherein said electron-emitting devices are located, and a region of said second substrate that is irradiated by said electrons, wherein said spacer has, in a vicinity of an end in a longitudinal direction, a portion shorter in a width direction of a gap between said first and second substrates rather than in another portion.
