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: 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 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.

Abstract: A method of manufacturing a display device capable of reducing tact time includes: a transfer step of arranging an anisotropic conductive adhesive layer provided on a base material that is transparent to laser light and a wiring board to face each other, and irradiating laser light from the base material side so that individual pieces of the anisotropic conductive adhesive layer are transferred to and arranged at predetermined positions on the wiring board; and a mounting step of mounting light-emitting elements on the individual pieces arranged at the predetermined positions on the wiring board. The individual pieces of the anisotropic conductive adhesive layer are able to be transferred and arranged with high precision and high efficiency by irradiation of laser light.

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: 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.
