Abstract
A carbon fiber mixed paper 8 obtained by mixing a fiber blend 7, which is obtained by knitting a carbon fiber and a glass fiber, into a paper material is used as the material for an anode that opposes to an electron emission cathode. A phosphor is applied onto this carbon fiber mixed paper 8, and further, an electrode 9 is provided. The present invention reduces heat generation at the anode as much as possible and enables uniform illumination without providing a diffuser. Moreover, the present invention does not require an electrode made of a transparent conductive film.
