further points to the following sections of the instant specification as
allegedly showing unexpected results [supplemental reply brief, page 4, ¶1]:
Page 2, lines 1-6:
However, the IPS type LCD has such problems that the
response of the liquid crystal is slow because of the structure
thereof, and the threshold voltage necessary between the
electrodes for changing the direction of the liquid crystal
is high, and furthermore, the luminance of the display panel
is low.
Page 3, lines 9-17:
Accordingly, it has become clear that even when a strong electric field
is generated near the TFT substrate, a weak electric field
is generated near the opposite substrate, and therefore, it
takes substantially a long time to rotate the liquid crystal.
It has been understood that when the cell gap is 4.5 µm, when
comparing the electric field intensity near the TFT substrate
and the electric field intensity near the opposite substrate,
the latter one is about half of the previous one.
Page 7, lines 9-23:
In the IPS-LCD, this ununiformity of the electric field
in the cell thickness direction has been the cause of such
problems that the response of the liquid crystal is slow, and
the threshold voltage necessary between the electrodes for
changing the direction of the liquid crystal is high, and
furthermore, the luminance of the display panel is low.
In both of the conventional example 1 and the conventional
example 2 the electric field becomes weaker in proportion to
the distance from the surface of the TFT substrate in the cell
thickness direction, but the method that makes it possible
to easily rotate the liquid crystal near the CF substrate in
which the electric field is weakened is not shown. Accordingly,
the conventional IPS mode LCD has still had the above-described
problems, because of the ununiformity of the electric field
in the cell thickness direction.
In particular, we note that appellant has failed to provide evidence
(i.e., an affidavit or declaration of record) to show how these portions of the
specification compare the claimed instant invention results to the closest
