distinguishes since Libman does not disclose a layer but
rather spaced reflective particles.” Although the color
filter in Libman is made of a “shallow, random, clumped,
discontinuous, open dispersion of contrast-enhancing
particles” (column 7, lines 35 through 39), the color filter
is still in the form of layers or elongate strips, albeit
porous layers or strips. Nothing in the claims on appeal
precludes a porous filter.
Appellants also argue (Brief, page 5) that “Libman does
not disclose a filter coating film which transmits light of
the color of its corresponding phosphor.” As indicated supra,
each of the color filters 98, 100 and 102 is of a color that
corresponds to the color of the light emitted by the
corresponding phosphors. Libman states (column 8, lines 47
through 51) that the light from the phosphors is transmitted
through openings 112 in the dispersion of pigment particles in
the color filters 98, 100 and 102. Nothing in the claims on
appeal precludes the transmission of light through openings in
each of the color filter layers.
