摘要： An image display element comprising a vacuum exterior container including a face plate and a back housing. A cathode is located within the vacuum exterior container. A control electrode controls electron beams projected from the cathode and a fluorescent layer generates light by projecting the electron beams, and a metal back layer provided on the fluorescent layer projects the light of fluorescent layer forward by the effect of specular gloss. A carbon layer is provided on the metal back layer to reduce the generation of backwardly scattered light. The metal back layer and carbon layer are provided by releasing from a supporter having mold release characteristics. The thickness of the metal back layer is determined in relation to the predetermined supply voltage such that the energy transmission factor of the reflected and dispersed electrons on the image display element is less than 30%.
