| titleOfInvention | Electron source and method of making the same |
| abstract | An electron source capable of suppressing consumption of an electron emission material is provided. According to the present invention, there is provided an electron source having an electron emission material and an electron emission confinement material covering a side surface of the electron emission material, the electron emission confinement material having a work function higher than that of the electron emission material , the thermal emissivity of the electron emission confinement material is lower than that of the electron emission material. |
