  • Patent number: 7435516
    Abstract: The present invention provides a photosensitive material for non-substrate liquid crystal display. This photosensitive material includes photo-initiator selected from the free-radical type or cation type photo-initiator or mixture thereof, photosensitive polymerizable monomers or oligomers selected from the group consisting of double-bond compounds, compounds having epoxy functional group and mixtures thereof, and modifier selected from the group consisting of long-alkyl-chain functional group, silicone-alkyl compounds, double-bond compounds and mixtures thereof. The photosensitive material can surround liquid crystal display cell and separate from assisting substrates that a non-substrate liquid crystal cell surrounded by photosensitive material is acquired.

  • Patent number: 7425282
    Abstract: A polymer liquid crystal device. The polymer liquid crystal device is fabricated by the following steps. A first substrate is provided, and a coating of a photosensitive composition is formed on the first substrate. Next, a second substrate is disposed on the first substrate. Finally, the coating is completely cured without a mask, forming a polymer dispersed liquid crystal film between the first and second substrate. Furthermore, the coating can also be cured with mask, forming a phase separation composite film between the first and second substrate.

  • Publication number: 20050107522
    Abstract: The present invention relates to a release agent for non-substrate liquid crystal display, comprising (a) 2-20 wt % of compounds selected from the group consisting of silicone, fluorine compounds and mixtures thereof, and (b) 0.5-30 wt % (based on the weight of (a)) of release modifier. The release agent is applied to the assisting substrates in the process of non-substrate liquid crystal display, so the assembled liquid crystal display element can be separated from the assisting substrates and a non-substrate liquid crystal display element is acquired.
