In relation to a polymerizable composition for forming a transparent optical resin layer to be interposed between an image display section of an image display device and a light-transmissive protective section thereof, the present invention provides a polymerizable composition that does not give rise to display defects caused by the deformation of the image display section, enables high-luminance, high-contrast image displaying, has excellent heat resistance, and also has a low dielectric constant. This polymerizable composition comprises: (1) a urethane (meth)acrylate obtained by reacting a hydrogenated polyolefin polyol and a compound having an isocyanato group and a (meth)acryloyl group; (2) a (meth)acryloyl-group-containing compound having a hydrocarbon group with a carbon number of 6 or greater; and (3) a photopolymerization initiator.
本发明涉及一种聚合物组合物,用于形成透明光学树脂层,以介于图像显示装置的图像显示部分和其透光保护部分之间。该聚合物组合物不会因为图像显示部分的变形而产生显示缺陷,能够实现高亮度、高对比度的图像显示,具有优异的耐热性,同时具有低介电常数。该聚合物组合物包括:(1)通过反应氢化聚烯烃多元醇和具有异氰酸酯基和(meth)丙烯酰基的化合物得到的聚氨酯(meth)丙烯酸酯;(2)具有碳数大于等于6的碳氢基团的(meth)丙烯酰基含有化合物;以及(3)光聚合引发剂。
