Document Type and Number:
WIPO Patent Application WO/2023/176628
Kind Code:
A1
Abstract:
The present invention provides an optical laminate that has stable optical characteristics even in harsh environments. According to an embodiment of the present invention, an optical laminate includes at least one optical member and at least one adhesive layer. When N is the total number of adhesive layers included in the optical laminate, α1 is the coefficient of linear expansion upon heating from 20°C to 30°C, and α2 is the coefficient of linear expansion upon cooling from 30°C to 20°C, at least N/2 of the adhesive layers are an adhesive layer A that satisfies 0.8≤α1/α2≤1.2.
