Problems solved by technology

[0008] However, although the curable composition using urethane acrylate has a large volume shrinkage rate (more than 4.0%) during curing, in addition, the use of maleic anhydride adducts of polyisoprene polymers and methacrylic acid The curable composition of the esterified product formed of 2-hydroxyethyl ester has a small volume shrinkage rate during curing, but there is a problem that the heat-resistant coloring property of the cured cured product is increased.

Abstract

Provided is a polymerizable composition for providing a thin image-display device that does not exhibit display problems due to deformation of an image-display unit, allows high-brightness, high-contrast image display, and tolerates heat well. A polymerizable composition for forming a polymer layer interposed between an image-display unit in an image-display device and a light-transmitting protective part. Said polymerizable composition is characterized by containing the following: (1) a (meth)acryloyl group-containing compound that has a structural unit derived from a (poly)ester polyol and / or a structural unit derived from a (poly)carbonate polyol; (2) a (meth)acryloyl group-containing compound that has a C9+ hydrocarbon group; and (3) a photopolymerization initiator.

Description

technical field [0001] The present invention relates to a polymerizable composition used in image display devices such as liquid crystal display devices such as smartphones and tablet PCs, a polymer obtained by polymerizing the composition, and a method for producing an image display device using the composition And an image display device manufactured by the manufacturing method. Background technique [0002] Conventionally, as such image display devices, for example, Figure 4 A liquid crystal display device 101 is shown. [0003] Such as Figure 4 As shown, this liquid crystal display device 101 has a transparent protective portion 103 formed of, for example, glass or plastic on a liquid crystal display panel 102 . [0004] In this case, in order to protect the surface of the liquid crystal display panel 102 and the polarizing plate (not shown), a spacer 104 is provided between the liquid crystal display panel 102 and the protective portion 103 by interposing the protect...
