Adhesive sheet, display device using the same, composition for forming adhesive layer used for production of adhesive film

Abstract

Provided are an adhesive sheet that can reduce reflectance, increase luminance and reduce thickness of a display device, a display device using the adhesive sheet, and a composition for forming adhesive layer used for producing the adhesive sheet. An adhesive sheet comprising a first adhesive layer containing an adhesive and a dye, and an ultraviolet absorbing layer laminated on one surface side of the first adhesive layer, wherein the dye contains a first coloring material having a maximum absorption wavelength in the range of 470 to 530 nm and a half width of the absorption spectrum of 15 to 45 nm, and a second coloring material having a maximum absorption wavelength in the range of 560 to 620 nm and a half width of the absorption spectrum of 15 to 55 nm, and the ultraviolet absorbing layer has an ultraviolet shielding rate of 85% or more according to JIS L 1925.
