Claims

[Scope of utility model registration request]

An envelope formed by sealing the anode substrate and the top plate includes an electrode having a fluorescent material, a spacer arranged at a constant interval, a grid for current control, and a filament as an electron emission source. 1. An i-optical display tube comprising: an insulating layer surface of an anode substrate and a grid frame of the spacer are fixed together with a frit sealing material at points other than the hermetically sealed portion.
