Title:
OPTICAL MULTILAYER BODY, OPTICAL MULTILAYER BODY WITH ADHESIVE LAYER, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/261120
Kind Code:
A1
Abstract:
This optical multilayer body 1 is provided with a glass plate 2, an adhesive layer 3 and an optical member 4 sequentially toward one side in the thickness direction. The adhesive layer 3 is in contact with a surface of the glass plate 2, said surface being on one side in the thickness direction, and a surface of the optical member 4, said surface being on the other side in the thickness direction. The optical member 4 has a thickness of 70 μm or less. The optical member 4 does not contain an adhesive layer. The bending resistance of the optical member 4 as obtained in accordance with the method A that is set forth in JIS L 1096 (2010) is 30 mm or more. The indentation elastic modulus of the adhesive layer 3 at 25°C as determined by a nanoindentation method is 1 GPa or more.
