Photocurable resin composition, image display device, and image display device manufacturing method

An image display device comprising an image display member, a cured resin layer, and a light transmitting member, in this order, the image display member including a polarizing plate that is in contact with the cured resin layer,

• wherein the cured resin layer has a water vapor transmission rate of 594 g/m2/day or more, at a thickness of 0.3 mm, and under a 40° C. and 90% relative humidity environment,
• wherein the cured resin layer is a cured product of a photocurable resin composition containing a monofunctional monomer that includes a heterocycle-containing (meth)acrylate monomer, and a (meth)acrylate resin, wherein the (meth)acrylate resin contains at least one of a polyether urethane (meth)acrylate oligomer and a polyester urethane (meth)acrylate oligomer, wherein a content of the heterocycle-containing (meth)acrylate monomer in the photocurable resin composition is 20 to 40% by mass,
• wherein the heterocycle-containing (meth)acrylate monomer contains a heterocycle selected from the group consisting of morpholine rings, furan rings and dioxalane rings, but is not tetrahydrofurfuryl (meth)acrylate, and
• wherein the polarizing plate includes a dyed polyvinyl alcohol resin-based polarizer, and has no visible discoloration even after the image display device is left in a 100° C. environment for 240 hours.
