Abstract
A display unit that includes an image display part and a light-transmitting protective part arranged on the image display part. A cured resin layer is arranged between the display part and the protective part. The cured resin layer can have a transmittance of 90% or higher in the visible range and a storage modulus at 25° C. of 1×107 Pa or less. The cured resin layer can be formed from a resin composition that has a cure shrinkage of 5% or less.
