LOW REFRACTIVE INDEX LAYER-CONTAINING ADHESIVE SHEET, METHOD FOR PRODUCING LOW REFRACTIVE INDEX LAYER-CONTAINING ADHESIVE SHEET, AND OPTICAL DEVICE

摘要

The present invention aims to provide a low refractive index layer-containing pressure-sensitive adhesive/adhesive sheet which is thin and has a low refractive index. In order to achieve the above object, the present invention provides a low refractive index layer-containing pressure-sensitive adhesive/adhesive sheet, the sheet including: a first pressure-sensitive adhesive/adhesive layer; a low refractive index layer; and a second pressure-sensitive adhesive/adhesive layer, the first pressure-sensitive adhesive/adhesive layer, the low refractive index layer, and the second pressure-sensitive adhesive/adhesive layer being laminated in this order, wherein the low refractive index layer has a refractive index of 1.25 or less.
