Title:
LIQUID CRYSTAL SEALING AGENT, METHOD FOR MANUFACTURING LIQUID CRYSTAL DISPLAY PANEL USING THE LIQUID CRYSTAL SEALING AGENT, AND LIQUID CRYSTAL DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2008/029893
Kind Code:
A1
Abstract:
This invention provides a liquid crystal sealing agent which can be applied to liquid crystal display panels. The liquid crystal sealing agent comprises (a) a compound containing a (meth)acryloyl group and a glycidyl group in its molecule and having a number average molecular weight of 500 to 2000, (b) a heat latent curing agent, (c) a radical polymerization initiator, and (d) a filler. The component (a), despite its high molecular weight, has high reactivity and latent curability, and thus simultaneously has a low level of solubility in liquid crystals, a high level of curability, and a high level of viscosity stability. Accordingly, the manufacture of a liquid crystal display panel using the liquid crystal sealing agent is advantageous in that, while maintaining the high level of productivity, the strength of adhesion between a substrate and a cured product of the liquid crystal sealing agent is high and the contamination of the liquid crystal can be suppressed on a low level, resulting in the manufacture of liquid crystal display panels which can realize a high level of display and a high quality.
