Abstract
PURPOSE:To provide a CRT having good charging preventive characteristic by making a glass film containing at least SiO2 or P2O5 as major components and including moisture absorptive metal salt of metal elements whose atomic number is below a specific value, and by putting this glass film on the outer surface of a front panel. CONSTITUTION:A front panel is equipped at its outer surface with a glass film containing at least SiO2 or P2O5 as major components and including moisture absorptive metal salt. Here the metal salt is of metal elements having an atomic number below 31. This metal salt is contained 0.001-10wt.% to the major components. This compound includes Si alcoholate or polysiloxane, and contains moisture absorptive metal salt 0.001-100wt.% of the weight of Si alcoholate or polysiloxane which are all converted into SiO2. The atomic model indicating this covering condition is given in the form of schematic diagram beside, where hollow and solid circles represent oxygen and silicon atoms, respectively, while greater solid circle a metal salt.
