Abstract
A thin image display device having a resin interposed between an image display unit and a protection member having a light-shielding member is manufactured. In the manufactured image display device, display defects caused by the deformation of the image display unit do not occur, and high-brightness and high-contrast display can be achieved. In addition, the resin in the area where the light-shielding member is formed can be sufficiently cured. The method for manufacturing an image display device includes the step of forming a cured resin layer by interposing a photo-curable resin composition between a base including the image display unit and a light-transmitting protection member including a light-shielding member 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 a visible range is used as the photo-curable resin composition. The photo-curable resin composition is photo-cured by irradiating it with rays of light at least…
