Abstract

The present invention provides a method for producing an image display device, a curable resin composition used in the method, and an image display device, the production method of which can obtain an optical display device that does not cause moire and has excellent visibility even when an arbitrary part is pressed. member. As a method of manufacturing an image display device, it includes the steps of defining a coating region of the first curable resin composition with the second curable resin composition, and applying the first curable resin composition to the coating region. step, and a step of curing the first curable resin composition to bond the liquid crystal display unit to the protective plate, and laminating a cured product layer obtained by curing the second curable resin composition on the sealing body. projected area, and not laminated on the projected area of ​​the polarizing plate. It is preferable that the said 1st curable resin composition or the said 2nd curable resin composition contains (meth)acrylate (A) and a photoinitiator (B).

Description

technical field

[0001] The present invention relates to a method for producing an image display device (hereinafter also referred to as an optical member) by bonding an optical base material having a light-shielding portion and another optical base material, and a curable resin composition used for the method. Background technique

[0002] In recent years, display devices in which a touch panel is bonded to a display screen of a display device such as a liquid crystal display, a plasma display, or an organic electroluminescent (EL) display to enable screen input have been widely used. This touch panel has a structure in which a glass plate or a resin film formed with a transparent electrode is bonded facing each other with a small gap, and a transparent protective plate made of glass or resin is bonded to the touch surface as necessary.

[0003] There is a technology of using a double-sided adhesive sheet for bonding a glass plate or film on which a transparent electrode is ...
