Optical components and image display devices with adhesive sheets and adhesive layers

Abstract

This invention provides an adhesive sheet that reduces noise, has sufficient adhesion, is drop-resistant, and transmits light over a wide wavelength range. The adhesive sheet 1 has an adhesive layer 10. The adhesive layer 10 does not peel off during drop-resistant testing, has a dielectric constant of 4 or less at 100 kHz, exhibits a glass adhesion of at least 10 N / 20 mm or more on at least one side under conditions of a peel angle of 180° and a tensile speed of 300 mm / min, and has a transmittance of 80% or more at both 380 nm and 420 nm wavelengths. The adhesive sheet 1 is used in optical components.
