Abstract
The present invention provides an optical pressure-sensitive adhesive sheet in which white turbidity is not caused by humidification and durability is excellent as well. The present invention provides an optical pressure-sensitive adhesive sheet, comprising: a pressure-sensitive adhesive layer in which a moisture ratio after storage under an environment of 60°C and 95% RH for 120 hours is 0.65 wt% or more, and a shear storage elastic modulus at 85°C which is measured by a dynamic viscoelastic measurement is 5.0 × 10<4>to 5.0 × 10<5>Pa, wherein a peeling distance measured by the constant-load peel test is 30 mm or less when an adherend is a polyethylene terephthalate plate, and the peeling distance measured by the following constant-load peel test is 30 mm or less when the adherend is an acrylic plate.
