Abstract
In the case where a pressure-sensitive adhesive sheet comprising a pressure-sensitive adhesive layer having a refractive index adjustment zone is provided in such a manner that two PET separators are laminated to opposite surfaces of the pressure-sensitive adhesive layer, it is difficult to distinguish between obverse and reverse sides of the pressure-sensitive adhesive sheet itself. The present invention is directed to solving the above problems and, specifically, to offering a pressure-sensitive adhesive sheet having a refractive index adjustment zone capable of being easily produced at low cost, in a state in which it is preliminarily laminated with a substrate provided with an electroconductive layer, thereby making it possible to resolve complexity in handling (to easily distinguish between one surface defined by the refractive index adjustment zone and the other surface defined by the remaining zone).
