being baked" (col. 3, lines 18-19). Two differences from
the subject matter of claim 1 are: (1) film 4 is Al O , not
2 3
SiO as claimed; and (2) film 4 is not disclosed to be an
2
"antireflection layer" as claimed, but is applied over the
carbon stripes as a protective layer to keep the carbon
layer from turning white during the baking process and to
avoid browning of the glass of the face plate due to the
electron beam (col. 1, lines 61-68; col. 3, lines 47-50;
col. 4, lines 3-5 and lines 16-23). Kato does not disclose
any optical properties of the film 4.
Iwasaki discloses a transparent inorganic film 5
interposed between the optical multilayered interference
film 2 and the face panel 1. The film 5 "does not function
as the optical thin film layer" (col. 5, lines 34-35).
"[T]he transparent inorganic material film 5 serves as a
barrier for preventing the optical thin film layer of
titanium dioxide (Ti0 ), a high-refractive-index film, from
2
effecting a chemical reaction directly with the glass
surface of the face panel 1 by virtue of the electron
energy." (Col. 5, lines 37-42.) "If silicon dioxide (SiO )

or aluminum oxide (Al O ) is used as the transparent
