Abstract:
1. A pressure-sensitive adhesive sheet, having: a total light transmittance of 85% or more; a light transmittance at a wavelength of 380 nm of 5% or less; and a haze of 3% or less, wherein the pressure-sensitive adhesive sheet comprises a pressure-sensitive adhesive layer comprising a triazine-based ultraviolet absorber and an acrylic polymer containing, as monomer units, at least one of an alkyl (meth)acrylate having a linear or branched alkyl group and an alkoxyalkyl (meth)acrylate, a monomer containing a hydroxyl group in a molecule thereof, and a monomer containing a nitrogen atom in a molecule thereof, wherein a proportion of the monomer containing a nitrogen atom in a molecule thereof is 1 to 30 wt % based on total monomer components (100 wt %) forming the acrylic polymer, and wherein a content of the triazine-based ultraviolet absorber is 1 to 10 parts by weight relative to 100 parts by weight of the acrylic polymer.
