Title:
LIGHT-SHIELDING SEALING AGENT FOR LIQUID CRYSTAL DISPLAY ELEMENT, TOP-TO-BOTTOM CONDUCTIVE MATERIAL, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/137749
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a light-shielding sealing agent for a liquid crystal display element, which can exhibit excellent adhesion strength to a substrate even after being exposed to a high-temperature and high-humidity environment; and a top-to-bottom conductive material and a liquid crystal display element, each of which is produced using the light-shielding sealing agent for a liquid crystal display element. The present invention is a light-shielding sealing agent for a liquid crystal display element which is a light-shielding sealing agent for use in a liquid crystal dropping process, comprising a curable resin that contains a curable compound having an unsaturated double bond, a radical polymerization initiator and a light-shielding agent, wherein the curable resin has a hydrogen-binding functional group value of 0.5 × 10-3 to 3.0 × 10-3 mol/g and titanium black is contained as the light-shielding agent.
