| 1. A self-luminous element comprising:
a vacuum hermetic envelope;
an electron source disposed inside said vacuum hermetic envelope;
a fluorescent substance layer disposed inside said vacuum hermetic envelope, for light emitting in response to electrons irradiated
from said electron source; and
a gas occlusion material disposed inside said vacuum envelope, said gas occlusion material containing ZrOx where 1≤x≤2, having oxygen defects, said gas occlusion material being disposed so as to be exposed to an atmosphere in said
hermetic enclosure;
wherein said gas occlusion material having a conductivity and containing graphite and ZrOx, where 1≤x≤2, having oxygen defects is exposed in an atmosphere inside said hermetic enclosure.
