Document Type and Number:
WIPO Patent Application WO/2015/186810
Kind Code:
A1
Abstract:
Provided is a sheet for an image display device, that enables easy and accurate adherence to the curved surface shape of a curved surface display, and prevents reductions in visibility. The sheet for an image display device is arranged on the surface side of an image display device, contains a cyclo-olefin copolymer as the main ingredient, and has a base layer containing, relative to 100 parts by mass of the cyclo-olefin copolymer, at least to 2 and at most 7 parts by mass of an elastomer having the same refractive index as the cyclo-olefin copolymer. Preferably, the average thickness of the base layer is at least 100µm and at most 500µm. Preferably, the water absorption of the base layer is 0.5% or less. Preferably, the tensile strength of the base layer is at least 40MPa and at most 70MPa. Preferably, the tensile extension of the base layer in the longitudinal direction thereof and at 25°C is at least 4% and at most 15% or less.
