the substrate. Color filters 14 are formed on the conductive
film. A second conductive film 15 is formed over the colored
layers. Finally a mask 16 is formed over the second conductive
film. We find all the layers to be transparent or light
transmitting. See Column 3, line 49 to column 4, line 13. We
find the conductive film 13 etched into a pattern of stripes as
required by the claimed subject matter. See column 4, lines 54-
55. We further find the mask 16 has a lattice pattern as
required by the claimed subject matter. See Figure 3. Hatano
is silent as to the composition of the substrate and uses a
resinous black pigment containing mask. Accordingly, Hatano
neither discloses that the substrate has an insulative surface
nor teaches a metal film as a light shielding layer.
Yanagisawa and EPA’412, both directed to liquid crystal
displays disclose glass substrates. See Yanagisawa, col 4, line
16, EPA’412, column 11, lines 43 -46, and examples 1, 6 and 7.
The examiner has found glass to be an insulative surface,

finding in their Reply Brief. See page 7. Accordingly, we agree
with and adopt this finding. Based upon the above
