摘要:
A thin display unit that incorporates a high-luminance, high-contrast display part that is free of image defects caused by the deformation of the display part is provided. The display unit of the present invention includes an image display part 2 and a light-transmitting protective part 3 arranged on the image display part 2. A cured resin layer 5 is arranged between the display part 2 and the protective part 3. The cured resin layer 5 has a transmittance of 90% or higher in the visible range and a storage modulus at 25°C of 1 × 10 7 Pa or less. The cured resin layer 5 is formed from a resin composition that has a cure shrinkage of 5% or less.
