摘要： An image forming apparatus comprises first and second substrates, a support frame arranged between the first and second substrates, and surrounding a space between the first and second substrates, electron emitting devices arranged on the first substrate facing the space, and an image forming member arranged on the second substrate. A spacer is disposed in the space between the first and second substrates, and a conductive film is arranged on the second substrate to surround the image forming member. The conductive film is supplied with a potential lower than that applied to the image forming member, and the spacer has a length greater than that of the image forming member. Each longitudinal end of the spacer is arranged between the inner periphery of the support frame and a respective plane through which a corresponding end of the conductive film extends perpendicularly to a principal surface of the second substrate.

摘要： An electron beam apparatus in which a spacer having a high-resistance film coating a surface of a base material is inserted between a rear plate having electron emitting elements and row-direction wires, and a faceplate having a metal back. The row-direction wires and the metal back are electrically connected via the high-resistance film. An electric field near an electron emitting element near the spacer is maintained to substantially constant irrespective of the positional relationship between the spacer and the electron emitting element near the spacer. When a sheet resistance value of the high-resistance film on a first facing surface of the spacer that faces a row-direction wire is represented by R1, and a sheet resistance value of the high-resistance film on a side surface adjacent to the electron emitting element is represented by R2, R2/R1 is 10 to 200.

摘要： In order to prevent a spacer from being charged by using a plate shaped spacer covered with a high resistance film, the present invention is aimed at preventing irregular displacements of electron beams emitted from adjacent electron-emitting devices and suppressing displacements of impinging positions of the electron beams emitted from the adjacent electron-emitting devices even with a slight displacement of an installation position of the spacer. The spacer is disposed along a row directional wiring. The high resistance film is allowed to come into contact with a metal back and the row directional wiring to achieve electrical connection therebetween. Contact portions between the high resistance film of the spacer and the row directional wiring are provided at predetermined intervals.

摘要： An image-forming apparatus, which consumes low electrical power and prevents discharge owing to the surfaces exposed onto the inside of a vacuum container at the time of image display, and can obtain a good image having high brightness, is disclosed. The image-forming apparatus comprises a rear plate provided with an electron source for emitting an electron, and a face plate provided with an image-forming member having an anode electrode, to which electric potential higher than the highest voltage to be applied to the electron source is applied, and a member for forming an image by being irradiated with electrons emitted from the electron source. And, a vacuum container is formed by arranging the rear plate and the face plate to be opposed to each other. At least a part of the surfaces exposed into the inside and the outside of the area in which the image-forming member is formed among the surfaces exposed into the vacuum container is covered with a high resistance film, and a sheet resistance value of one part of the high resistance film which is situated on the inside of the area where the image-forming member is formed is lower than that of another part of the high resistance film which is situated on the outside of the area where the image-forming member is formed.
