Abstract: A pressure-sensitive adhesive sheet comprises a support and a transparent pressure-sensitive adhesive layer on the support. The pressure-sensitive adhesive layer comprises a base adhesive zone made essentially of a transparent base pressure-sensitive adhesive material and formed over a given range from a first principal surface of the pressure-sensitive adhesive layer in a thickness direction of the pressure-sensitive adhesive layer, and a transparent, adherent, refractive index-adjusting zone formed over a given range from a second principal surface of the pressure-sensitive adhesive layer in the thickness direction, and wherein the refractive index-adjusting zone has a refractive index greater than a refractive index of the base pressure-sensitive adhesive material.
