Abstract
A method for manufacturing an image display device includes the step of forming a cured resin layer 15 by interposing a photo-curable resin composition between a base 2 including an image display unit such as a liquid crystal display panel 8 and a light-transmitting protection member 3 including a light-shielding member 5 and then photo-curing the photo-curable resin composition. In this method, a resin composition having a curing shrinkage ratio of 5% or less, yielding a cured product having a storage elastic modulus at 25° C. of 1.0×107 Pa or less, and forming the cured resin layer having a light transmittance of 90% or more in the visible range is used as the photo-curable resin composition.

A method for manufacturing an image display device, the method comprising the step of forming a cured resin layer by interposing a photo-curable resin composition between a base including an image display unit and a light-transmitting protection member including a light-shielding member and then photo-curing the photo-curable resin composition, wherein
- a resin composition including an acrylic monomer, a photo polymerization initiator, and one of an oligomer and a polymer, having a curing shrinkage ratio in the range of 1.0 to 4.5%, yielding a cured product having a storage elastic modulus at 25° C. of 4×103 to 1×106 Pa, and forming the cured resin layer having a light transmittance of 90% or more in a visible range is used as the photo-curable resin composition, wherein
- the method further comprises the step of interposing a curable resin composition containing a thermal polymerization initiator including an organic peroxide at least between the light-shielding member and the base and heating the curable resin composition, and wherein
- the curable resin composition containing the thermal polymerization initiator and interposed between the light-shielding member and the base is the photo-curable resin composition.
A method for manufacturing an image display device, the method comprising the step of forming a cured resin layer by interposing a photo-curable resin composition between a base including an image display unit and a light-transmitting protection member including a light-shielding member and then photo-curing the photo-curable resin composition, wherein
- a resin composition including an acrylic monomer, a photo polymerization initiator, and one of an oligomer and a polymer, having a curing shrinkage ratio in the range of 1.0 to 3.8%, yielding a cured product having a storage elastic modulus at 25° C. of 1×104 to 4×105 Pa, and forming the cured resin layer having a light transmittance of 90% or more in a visible range is used as the photo-curable resin composition, wherein
- the method further comprises the step of interposing a curable resin composition containing a thermal polymerization initiator including an organic peroxide at least between the light-shielding member and the base an heating the curable resin composition, wherein
- the photo-curable resin composition interposed between a non-light-shielding portion of the protection member and the base does not contain a thermal polymerization initiator, and wherein the photo-curable resin composition containing the thermal polymerization initiator and interposed between the light-shielding member and the base is irradiated with light and heated.
