Abstract
An optical laminate includes two substrates each of which has a tensile modulus in a range from 2,000 MPa to 7,500 MPa, and an adhesive layer interposed between the substrates. A storage modulus at 25° C. of the adhesive layer is 100 kPa or less, and a storage modulus at −20° C. of the adhesive layer is equal to or less than three times the storage modulus at 25° C. of the adhesive layer. The optical laminate and an image display device including the optical laminate may have an improved flexible property at various temperature ranges and may be capable of minimizing cracks when being bent.
