Abstract: A method for manufacturing an image display device capable of suppressing lifting phenomenon including: step (A): applying a photocurable resin composition to surfaces of a light transmitting optical member or an image display member forming a photocurable resin composition layer; step (B): irradiating the photocurable resin composition layer with light to form a pre-cured resin layer; step (C): bonding the image display member and the light transmitting optical member via the pre-cured resin layer; step (D): obtaining an image display device by irradiating light to the pre-cured resin layer to final-cure the pre-cured resin layer, thereby laminating the image display member and the light transmitting optical member via the light transmitting cured resin layer.

Abstract: A method for manufacturing an optical member which can improve bonding properties between a first member having a light transmitting property and a second member. The method includes a precuring step of forming a photocuring precured resin layer on a surface of the first member or the second member, the photocuring precured resin layer having a thin film on a side to be bonded with the second member or the first member, a bonding step of bonding the first member and the second member via the precured resin layer, and a final curing step of final-curing the precured resin layer to form a light transmitting resin layer. It is thereby possible to reduce the elastic modulus of the precured resin layer, suppress protrusion during bonding, and improve bonding properties.
