Abstract
The present invention provides an excellent optical pressure-sensitive adhesive sheet having an excellent adhesion property to an optical member. The present invention relates to an optical pressure-sensitive adhesive sheet comprising a pressure-sensitive adhesive layer, wherein a relative dielectric constant at a frequency of 1 MHz is 5 to 10, and an adhesion strength to a glass, which is measured with a peel angle of 180° and a tensile speed of 300 mm/min after 30 min of laminating the optical pressure-sensitive adhesive sheet to the glass, is 3 N/20 mm to 15 N/20 mm.
