thick -- vacuum enclosure was carried out at the 12-micrometer cell (20x20mm of
viewing areas) Then, using the black light, by irradiating for 120 seconds by the
irradiation intensity of l5 mW/cm2, a monomer and oligomer were hardened
(radical polymerization), 2 phase separation of macromolecule matrices was
considered as liquid crystal, and the PDLC element was created. The given energy
is equivalent to 1800 mJ/cm2. The obtained element showed the good dispersion
state in the state where voltage is not impressed. (brackets in original).
(0021)
(Effect of the Invention) As explained above, the luminosity of projected type
display of this invention is improving sharply by use of unnecessary PDLC of a
polarizing plate. When it applies to projected type display while driver voltage fell
sharply, consequently the drive of PDLC furthermore used for this invention with
TFT or an MIM element was attained, it is bright and the clear high image display
of a contrast ratio is possible for it.
Opinion
During examination, the Office bears the initial burden of establishing a prima facie case
of obviousness. In re Bell, 991 F.2d 781, 783, 26 USPQ2d 1529, 1530 (Fed. Cir. 1993). Thus,
the Office must establish that the one of ordinary skill in the art would have selected the
appropriate materials from the prior art and combine them in the manner claimed by Serbutoviez.
Serbutoviez’s claim 5 is directed to a polymerizable mixture whereas claim 9 is directed
to a display device having a cell manufactured from a polymerizable mixture. The polymerizable
mixtures recited in Serbutoviez’s claims 5 and 9 are said to contain:
two types of non-volatile reactive monomers, the first type of monomer being an
ethoxylated acrylate and readily miscible with a liquid crystalline material and the
second type of monomer being poorly miscible with said liquid crystalline
material.
