Abstract:
An electron-emitting device includes an electron-emitting film containing molybdenum. A spectrum obtained by measuring a surface of the electron-emitting film by X-ray photoelectron spectroscopy has a first peak having a peak top in the range of 229±0.5 eV and a sub peak having a peak top in the range of 228.1±0.3 eV.
