Abstract
An image-forming apparatus comprises a rear plate on which an electron-emitting device is provided, a face plate having an image-forming member and arranged to be opposed to the rear plate, and a spacer provided between the face plate and the rear plate. The spacer comprises a spacer base plate and a coating layer including organic resin and carbon. At least part of the carbon is exposed from the surface of the coating layer. The image-forming apparatus displays an image with a high luminance and a high color saturation over a prolonged time.

An image-forming apparatus comprising:
- a rear plate on which an electron-emitting device is provided;
- a face plate having an image-forming member and arranged to be opposed to the rear plate;
- and
- a spacer provided between the face plate and the rear plate;
- wherein the spacer is formed by covering a spacer base material with organic resin and carbon;
- and
- the spacer has a surface including the carbon.
An image-forming apparatus comprising:
- a rear plate on which an electron-emitting device is provided;
- a face plate having an image-forming member and arranged to be opposed to the rear plate;
- and
- a spacer provided between the face plate and the rear plate;
- wherein the spacer is formed by covering a spacer base material with organic resin;
- and
- the spacer base material is formed by dispersing at least one fibrous filler selected from glass, alumina, boron, carbon, and ceramics-based whiskers, in organic resin.
An image-forming apparatus comprising:
- a rear plate on which an electron-emitting device is provided;
