Document Type and Number:
WIPO Patent Application WO/2022/158044
Kind Code:
A1
Abstract:
Provided are: an adhesive sheet capable of enabling a display device to have a low reflectance, a high brightness, and a thin shape; a display device using said adhesive sheet; and an adhesive layer-forming composition for use in production of said adhesive sheet. This adhesive sheet is characterized by being provided with a first adhesive layer containing an adhesive agent and a dye, and an ultraviolet ray absorbing layer laminated on one surface side of the first adhesive layer, and is characterized in that the dye contains a first coloring material that has a maximal absorption wavelength in the range of 470-530 nm and that has an absorbance spectrum in which the half width is 15-45 nm and a second coloring material that has a maximal absorption wavelength in the range of 560-620 nm and that has an absorbance spectrum in which the half width is 15-55 nm, and the ultraviolet-ray blocking rate, in compliance with JIS L 1925, of the ultraviolet ray absorbing layer is at least 85%.
