Abstract

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.

Description

technical field [0001] The present invention relates to a polymerizable composition used in image display devices such as liquid crystal display devices used in smartphones, tablet PCs, etc., polymers obtained by polymerizing the composition, and production of image display devices using the composition method and an image display device manufactured by the manufacturing method. Background technique [0002] Currently, in smartphones and tablet PCs, operations using a touch panel are generally performed. This touch panel also serves as a display screen, and such an image display device generally has a layered structure of a light-transmitting protective portion / touch sensor / image display portion such as LCD and organic EL in order from the surface. In this layer structure, for the purpose of protecting each layer and preventing reflection and scattering of light between layers, a transparent optical resin layer is usually present between all or part of the layers. In addit...
