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 1×10Pa or less. The cured resin layer can be formed from a resin composition that has a cure shrinkage of 5% or less.

Resin composition and display unit

A thin image display device is provided which is free from display defects caused by the deformation of an image display part and can display high brightness and high contrast images. The image display device includes an image display part, a light-transmitting protective part arranged on the image display part, and a cured resin layer interposed between the image display part and the protective part. The cured resin layer has a light transmittance in the visible region of 90% or more and a refractive index (nD) of 1.45 or more and 1.55 or less.

Exemplary embodiments enable a high-luminance and high-contrast image to be displayed so that there are no defects resulting from deforming an image display part, the curable resin composition has a uniform thickness, and air bubbles are prevented in the curable resin composition. A method for producing an image display apparatus includes coating a curable resin composition onto a base and/or protective part, arranging the base and the protective part to face each other, and forming a cured resin layer between the base and the protective part, wherein the curable resin composition has a curing shrinkage ratio of 5% or less and includes polyurethane acrylate and isobornyl acrylate, and the cured resin layer has a storage modulus of 1&#xd7;10Pa or less at 25&#xb0; C. and a light transmittance in a visible region of 90% or more, and wherein the curable resin composition coated onto the base or the protective part has a pattern with a prescribed shape.

An image display device, and a production method thereof are provided, which maximize suppression of warping of a protective panel. A liquid crystal display panel and a transparent protective panel formed from a plastic are arranged facing each other via a cured resin. An outer dimension of the protective panel is made larger than an outer dimension of the display panel. Curing is carried out with an edge of the protective panel fixed with a fixing jig during and after curing. Alternatively, the outer dimension of the protective panel is substantially equal to an outer dimension of the display panel, which is substantially equal to an inner dimension of a case and the protective panel. Curing is carried out with the resin composition in contact with substantially the whole face of the protective panel.
