Abstract

The present invention provides an optical pressure-sensitive adhesive sheet excellent in anti-foaming release property in which whitening due to humidification hardly occurs. The invention relates to an optical pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer formed from a pressure-sensitive adhesive composition including: an acrylic polymer (A) which has a weight average molecular weight of 100,000 to 3,000,000 and is formed from a component including, as essential monomer components, a monomer having a nitrogen atom in a molecule thereof and a monomer having a hydroxyl group in a molecule thereof; and an acrylic polymer (B) having a weight average molecular weight of 1,000 to 30,000.
