Title:
OPTICAL LAMINATE, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/261101
Kind Code:
A1
Abstract:
An optical laminate 1 comprises, a glass plate 2, a bonding layer 3, and a protective member 4 in that order toward one side in the thickness direction. The bonding layer 3 is in contact with: a surface on one side in the thickness direction of the glass plate 2; and a surface on another side in the thickness direction of the protective member 4. The ratio of the elastic modulus of the bonding layer 3, as measured using the nanoindentation method, to the thickness of the bonding layer 3 is 1.0 x 104 [Pa/μm] or more. The ratio of the elastic modulus of the protective member 4, as measured using the nanoindentation method, to the thickness of the protective member 4 is 1.0 x 108 [Pa/μm] or more.
