Claim:
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 an acrylic polymer and a hydroxyphenyl triazine-based UV absorber, wherein the acrylic polymer contains, as a monomer unit, at least one of an alkyl (meth)acrylate having a linear or branched alkyl group and an alkoxyalkyl (meth)acrylate, wherein the acrylic polymer contains, as a monomer unit, a monomer containing a hydroxyl group in a molecule thereof, wherein the proportion of the monomer containing a hydroxyl group in a molecule thereof is at least 13 wt % based on total monomer components (100 wt %) forming the acrylic polymer, and the total light transmittance, light transmittance at 380 nm, and haze being measured wherein the pressure sensitive adhesive sheet has a thickness of 50 μm; wherein the acrylic polymer contains, as a monomer unit, a monomer containing a nitrogen atom in a molecule thereof; and wherein the 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.
