ABSTRACT:
A carbon fiber mixed paper8obtained by mixing a fiber blend7, 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 paper8, and further, an electrode9is 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.
