Problems solved by technology

With the thinning of such liquid crystal display devices, the rigidity of the liquid crystal panel decreases, and due to the increase in size, the panel tends to warp structurally.
Therefore, the problem caused by the warpage of the panel becomes significant as the moisture permeability of the use environment changes

Abstract

The present invention relates to a hard coat film, a method for producing the hard coat film, an antireflection film, a polarizer, and an image display device. The present invention provides a hard coat film having low moisture permeability, sufficient surface hardness, and excellent productivity. The hard coat film of the present invention has a hard coat layer on at least one side of a transparent support, and the hard coat layer is composed of an ethylenically unsaturated double bond group having a cycloaliphatic hydrocarbon group and having more than 3 ethylenically unsaturated double bond groups in the molecule. A hard coat-forming composition comprising a group compound and a polymerization initiator is formed.

Description

technical field [0001] The present invention relates to a hard coat film, a method for producing the hard coat film, an antireflection film, a polarizer, and an image display device. Background technique [0002] Liquid crystal display devices (LCDs) are widely used due to their thin thickness, light weight, and low power consumption. A liquid crystal display device includes a liquid crystal unit and a polarizer. A polarizing plate is usually composed of a protective film and a polarizing film, and is obtained by dyeing a polarizing film composed of a polyvinyl alcohol film with iodine, stretching it, and laminating the protective films on both surfaces thereof. In a transmissive liquid crystal display device, the polarizer is usually installed on both sides of the liquid crystal cell, and then one or more optical compensation films (retardation film) are arranged inside the two polarizers (on the liquid crystal cell side). In addition, an optical compensation film may als...
