The monomer of ultraviolet-rays hardenability, oligomer, and by irradiating
ultraviolet rays, a mixed solution is further enclosed in a cell from a nematic
liquid crystal, and the radical polymerization of a monomer and the oligomer is
carried out, and the liquid crysta[l] display element by this invention fixes the
phase separation of a liquid crystal layer and a macromolecule layer, and is
obtained. The size of a liquid crystal layer is controlled by the temperature at the
time of a polymerization, and optical irradiation intensity at this time. As a
monomer material, the single organic-functions acrylate monomer expressed with
a general formula 1 [a nonyl-phenol EO acrylate having 3 to 9 ethylene oxide
units] from the interaction in an interface being weak and low-battery-ization
being achieved is desirable after that compatibility with the liquid crystal before
hardening is good, and hardening. Moreover, only by the single organic-functions
acrylate monomer, since hardenability is bad and control of phase separation
structure is difficult, PDLC suitable for the display device is formed by using
together the good acrylic ester oligomer of compatibility with liquid crystal. In
order to demonstrate both function in addition especially, as for monomer
material, it is desirable that it is 20 - 70 % of the weight to a macromolecule
matrix. (brackets added)

(Example) Drawing 1 is the cross section of the liquid crystal display element by
this invention. The inside of drawing and 1 are the macromolecule matrices in
which an MIM element and 5 were formed in of the nematic liquid crystal, and 6
was formed [ PDLC and 2 / a glass substrate and 3 ] for a transparent electrode
(lTO) and 4 of the radical polymerization. In the state of no voltage impressing,
PDLC is in a light-scattering state and changes to a light-transmission state by
impressing voltage. (brackets in original)

(Example 1) PDLC by this invention was created using the following
composition.
- Nonyl-phenol EO denaturation acrylate 12wt% (SN[ by Sannopuko, Inc. ]- 5
X-1626, n= 4)
- Acrylic acrylic oligomer 12wt% (the Toagosei chemical-industry company make
—6200)
- Photopolymerization initiator 1wt% (2, 4-diethyl thioxan ton)
- Nematic liquid crystal 75wt% (MJ90657 by Merck Co.)
the above-mentioned composition – **** -- the temperature up of the mixed
solution was carried out to 100 degrees C, and it was made into the compatible
state the cell by which ITO electrode formation was carried out in this solution --
