Estimating the term…
The present invention provides an optical pressure-sensitive adhesive sheet which can control the change in capacitance, which cause malfunction, when the optical pressure-sensitive adhesive sheet is applied to an optical member. The present invention provides an optical pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer, wherein a relative dielectric constant at a frequency of 1 MHz is 2 to 8, and a dielectric tangent at a frequency of 1 MHz is more than 0 and 0.2 or less.
