ABSTRACT:
An electron beam display device which has high contrast and excellent image quality, by eliminating halation due to re-collision of the electrons in the fluorescent element area. The electron beam display device includes a face glass on which an image is formed, a cathode for emitting electron beams, a fluorescent element layer on the face glass and facing the cathode, with which layer electron beams collide to emit light for forming an image on the face glass, an aluminum layer as anode on the fluorescent element layer, and a carbon layer on the aluminum layer, having a thickness sufficient to prevent electrons, reflected in the aluminum anode layer by collision of electron beams with the aluminum anode layer, from coming back into the face glass.
