Abstract: An image display device is manufactured by: applying a liquid photo-curable resin composition having a total value of cure shrinkage ratios based on pre-curing and complete curing of 3% or more to a surface of the light-transmitting cover member or a surface of the image display member with a thickness greater than that of the light-shielding layer to cancel the step between the light-shielding layer and the light-shielding layer forming surface of the light-transmitting cover member; pre-curing the photo-curable resin composition with the irradiation of ultraviolet rays to form a pre-cured resin layer; bonding the light-transmitting cover member to the image display member such that the pre-cured resin layer is placed inside; and subjecting the pre-cured resin layer to the irradiation of ultraviolet rays to achieve the complete curing thereof. The pre-curing is conducted to obtain a cure shrinkage ratio less than 3% in the complete curing thereof.

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.

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: A method for quickly applying and spreading adhesive between substrates without leaving air bubbles. The method includes holding two substrates apart from each other with adhesive sides facing, a second substrate being positioned above a first substrate. The second substrate is suspended in a manner so as to cause a portion to warp towards the first substrate. After a liquid filler is applied between the two substrates, rollers are lowered onto the second substrate and moved so as to disperse the liquid filler between the first and second substrates. In accordance with the rolling of the rollers, end portions of the second substrate are lowered towards the first substrate.

Abstract: A liquid photocurable resin composition not containing a thermal polymerization initiator is applied to a surface of a light-transmitting cover member having a light-shielding layer or a surface of an image display member, irradiated with ultraviolet rays under an atmosphere where the oxygen concentration is significantly decreased and cured, to form a light-transmitting cured resin layer. Subsequently, the image display member and the light-transmitting cover member are stacked through the light-transmitting cured resin layer to manufacture an image display device of the present invention.
