Title:
LIQUID CRYSTAL SEALING AGENT AND PRODUCTION METHOD FOR LIQUID CRYSTAL DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2016/013214
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a liquid crystal sealing agent that has a uniform line width even in a fine seal pattern, that can bond two substrates at a high bonding strength, and that does not easily leak liquid crystals. In order to solve said problem, the present invention provides a liquid crystal sealing agent that includes (1a) a (meth)acrylic resin or (1b) a (meth)acryl-modified epoxy resin that has, in the molecule thereof, an epoxy group and a (meth)acrylic group, (2) an organic filler (A) that has an average particle size of 4-13 μm, (3) an organic filler (B) that has an average particle size of 0.05-1 μm, and (4) a radical polymerization initiator, wherein, when the content (mass) of component (2) is W1 and the content (mass) of component (3) is W2, 0.25 ≤ W1/(W1 + W2) ≤ 0.75.
