摘要:
An image formation apparatus is disclosed which includes, within an enclosure configured by a pair of substrates placed face to face and an external frame placed between the substrates, an electron source placed on one of the pair of substrates, an image formation material placed on the other substrate, and spacers placed between the substrates, characterized in that the spacers and the external frame is conductive and device is provided for electrically connecting the spacers and the external frame so that the equipotential surfaces between the spacers and the external frame are quasi-parallel when driven.

A spacer on which static electricity is restricted and an electron beam apparatus in which the spacer is provided. In the electron beam apparatus comprising an electron source provided with electron emission devices, a face plate provided with anodes and spacers installed between the electron source and the face plate, unevenness is formed on the surface of the spacer substrate, and further a thin film which has a smaller thickness than a roughness. This makes possible the restriction of incident angle multiplication coefficient for the primary electrons whose energy is lower than the second cross-point energy of a resistive film. The electron beam apparatus provided with the above spacer is excellent in display definition and long-term reliability since the display of light emission points and the creeping discharge accompanying the static electricity can be restricted due to the spacer.

An electron beam emitting apparatus has a first plate with an electron-emitting device 15, and an electrode 8 opposed to the first plate, and the electrode 8 is applied a potential to accelerate electrons emitted from the electron-emitting device 15. In the electron beam emitting apparatus, a potential defining region 9 is provided a surface of the first plate on the electrode 8 side and a first potential defining region forming the potential defining region 9 is provided in a projective area of the electrode 8 onto the potential defining region 9; and, where d represents a distance between the electrode 8 and the potential defining region 9, an additional potential defining region is defined in the range of 0.83d in all directions parallel to the first plate from the edge of the projective area of the electrode 8 onto the potential defining region 9. This stabilizes trajectories of electrons and permits an excellent image to be formed without deviation of light emission positions.

This invention provides an arrangement for alleviating the electric charge of members apt to be electrically charged such as spacers used in an electron beam apparatus by arranging a high resistance film thereon. Particularly, the low resistance layer arranged at each of the members is covered by a high resistance film to suppress any electric discharges.

There are provided an electron beam device which has an atmospheric pressure-resistant member such as a spacer interposed between an electron source and a member to be irradiated with electrons, and can suppress charge on the member, a charging-suppressing member, and its producing method. An electron beam device having an electron source for emitting electrons, a member to be irradiated with the electrons, and a first member interposed between the electron source and the member to be irradiated is characterized in that the surface of the first member has a three-dimensional shape, and projecting portions of the three-dimensional shape form a network shape. In addition, an electron beam device having an electron source for emitting electrons, a member to be irradiated with the electrons, and a first member interposed between the electron source and the member to be irradiated is characterized in that the surface of the first member has a three-dimensional shape, and the three-dimensional shape has recessed portions continuously surrounded by projecting portions.
