liquid crystal display" (column 4, lines 22 through 30).
Based upon the teachings of Kim, the examiner concludes
(Answer, page 4) that "it would have been obvious to apply the
teaching of Kim to the teaching of admitted prior art (fig 13)
to make the spacer in a predetermined pattern since doing so
is not only just one of many ways to make the spacers between
two different layers in the LCD system, but also it is one of
the steps in making uniform thickness of a liquid crystal
display a possibility as specified by Kim."
For the advantage of improved contrast, we agree with the
examiner that it would have been obvious to one of ordinary
skill in the art to locate the spacers/particulates 209 in the
admitted prior art (Figure 13) in a predetermined pattern in
the non-display/black stripe region as taught by Kim (column
2, lines 45 through 49 and column 4, lines 46 through 49).
Notwithstanding our agreement with the examiner,
appellants have correctly argued (Reply Brief, page 3) that:
Kim, since it is not addressed to a plasma addressed
LCD wherein an intermediate sheet spans across
barrier ribs in an underlying plasma chamber, does

are not adhesively attached to any intermediate
