An adhesive composition for an organic EL display device, an adhesive layer for an organic EL display device, a polarizing film comprising an adhesive layer for an organic EL display device, and an organic EL display device

摘要

The present invention is a pressure-sensitive adhesive layer for an organic EL display device formed of a pressure-sensitive adhesive composition containing a (meth) acrylic polymer and an ultraviolet absorber, and the (meth) acrylic polymer is an alkyl (meth) acrylate having an alkyl group having 8 or less carbon atoms. (A) and an alkyl (meth) acrylate having an alkyl group having 12 to 24 carbon atoms (B), wherein the ratio (a) and the ratio (b) of (B) in (A) are Formula (1): 60≤ {(a) + (b)}, Equation (2): 1.4≤ {(a) / (b)} ≤2 In addition, the pressure-sensitive adhesive layer has a Tg of -20 to -5 ° C, a transmittance of 380 nm in wavelength of 10% or less, a transmittance of 450 nm in wavelength of 85% or more, a total light transmittance of 85% or more, and haze 1% or less. The pressure-sensitive adhesive layer for an organic EL display device of the present invention can suppress deterioration of an organic EL element, has high transparency, has low dielectric properties, and is excellent in peeling resistance during drop impact.
