Abstract
An 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 2, a light-transmitting protective part 3 arranged on the image display part, and a cured resin layer 5 interposed between the image display part 2 and the protective part 3. The cured resin layer 5 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.
Claims18
An image display device, comprising an image display part and a light-transmitting protective part arranged on the image display part, wherein
- the image display device further comprises a cured resin layer arranged between the image display part and the protective part;
- the cured resin layer has a light transmittance in a visible region of 90% or more and a refractive index (nD) of 1.45 or more and 1.55 or less;
- the cured resin layer is a cured product of a photocurable resin composition comprising at least one kind of polymer, at least an acrylate monomer, and a photopolymerization initiator, and having a curing shrinkage ratio of 5% or less;
- a first polarizing plate and a second polarizing plate are arranged on the surfaces of the image display part, the cured resin layer being disposed on the first polarizing plate;
- and
- a spacer is disposed between the image display part and the light-transmitting protective part, and the spacer surrounds a periphery of the cured resin layer.
A resin composition for forming a cured resin layer that is arranged between an image display part of an image display apparatus and a light-transmitting protective part, the resin composition having a curing shrinkage ratio of 5.0% or less, a cured resin formed by curing the resin composition having a transmittance in the visible region of 90% or higher and the resin composition having a refractive index (nD) of 1.45 or more and 1.55 or less and a storage modulus at 25° C. is 1.0×107 or less, wherein
- the resin composition contains at least one kind of polymer, at least one kind of an acrylate monomer, and a photopolymerization initiator;
- a first polarizing plate and a second polarizing plate are arranged on the surfaces of the image display part, the cured resin layer being disposed on the first polarizing plate;
- and
- a spacer is disposed between the image display part and the light-transmitting protective part, and the spacer surrounds a periphery of the cured resin layer.
