Title:
CATHODE BODY AND SURFACE-EMITTING FLUORESCENT DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP2009211969
Kind Code:
A
Abstract:

To solve a problem that a surface-emitting fluorescent light-emitting device is in a situation where sufficient electron emission efficiency cannot be obtained.

A cathode electrode having an electron emission layer can be obtained by using a material having smaller work function than that of an electrode formed by a metal material. By interposing a thin film having smaller resistivity than that of the electron emission layer between the electron emission layer and the electrode, the electron emission efficiency can be improved further.
