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.

Abstract: According to a method of manufacturing an image display device of the present invention, a photo-curable resin composition in a liquid state is applied to a surface of a light-transmitting cover member including a light-shielding layer or a surface of the image display member to a thickness greater than that of the light-shielding layer. Then, in this state, the photo-curable resin composition is irradiated with a UV ray to be pre-cured, thereby forming a pre-cured resin layer. Next, the image display member and the light-transmitting cover member are stacked via the pre-cured resin layer and thereafter, the pre-cured resin layer is irradiated with a UV ray to be completely cured, thereby forming a light-transmitting cured resin layer.

Abstract: In the method of manufacturing an image display apparatus according to the present invention, a liquid photocurable resin composition that does not contain a thermal polymerization initiator is coated on the surface of a light-transmissive cover member including a light shielding layer or the surface of an image display member in a thickness thicker than that of the light shielding layer, and thereafter UV rays are irradiated in that state for curing to form a light-transmissive cured resin layer. Then, the image display member and the light-transmissive cover member are laminated to each other via the light-transmissive cured resin layer to obtain an image display apparatus.
