Abstract
A carbon fiber mixed paperobtained by mixing a fiber blend, 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, and further, an electrodeis 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.
