Patent ID: 8142591

Claim:
A method for producing liquid crystal display element without substrates, comprising following steps: manufacturing a first assisting substrate containing a release agent layer and a cured photosensitive material layer with an electrode pattern, wherein said cured photosensitive material layer is applied on said release agent layer and said electrode pattern is fabricated on said cured photosensitive material layer; manufacturing a second assisting substrate containing a release agent layer, a cured photosensitive material layer with an electrode pattern, an alignment layer, and a photo-polymerizable mixture which comprises a photosensitive material and a liquid crystal material; wherein said cured photosensitive material layer is applied on said release agent layer, said electrode pattern is fabricated on said cured photosensitive material layer, said alignment layer is applied on said cured photosensitive material layer and said electrode pattern and said photo-polymerizable mixture is applied on said alignment layer; assembling said first assisting substrate and said second assisting substrate and exposing said photo-polymerizable mixture to UV light through a mask to form a plurality of polymer walls between said first assisting substrate and said secondary assisting substrate, wherein said polymer walls surrounding said liquid crystal; and peeling off said first assisting substrate, said second assisting substrate and their respective release agent layer to form a liquid crystal display element without substrates; wherein said release agent layer is formed by coating a release agent on said first and second assisting substrate, respectively, and said release agent comprising: (a) 2-20 wt % of compounds selected from the group consisting of silicone, fluorine compounds and mixtures thereof (b) 0.01-0.6 wt % of release modifier; and (c) a solvent as a complement to 100 wt %; and wherein said release modifier is a silicon release modifier selected from the group consisting of: (i) a silicone compound having the following linear molecular structure: wherein R 1 is C 1-3 alkyl; R 2 is hydrogen atom, C 1-3 alkyl or C 2-10 alkenyl; R 3 is C 1-3 alkyl or phenyl; said silicone compound has molecular weight of 3,500˜30,000; when calculated by molecular weight, (—Si(R 1 )(R 1 )O—) m accounts for 55˜100% of silicone compound, (—Si(R 1 )(R 2 )O—) n accounts for 0˜15%, (—Si(R 1 )(R 2 )O—) 0 accounts for 0˜15%, and (—Si(R 3 )(R 3 )O—) p accounts for 0˜15%, and (ii) a compound having the following cage molecular structure: ((R 4 )SiO 1.5 ) q (II) wherein R 4 is hydrogen atom or C 2-10 alkenyl; and q is an integer from 8 to 16.
