Abstract: Disclosed is an optical laminate roll formed of a long optical laminate including a glass layer. In the optical laminate roll, the optical laminate includes a flexible glass layer (10), a polarize (30) and a pressure sensitive adhesive layer (80). The thickness of the glass layer is preferably 150 μm or less. The length of the optical laminate roll is preferably 100 m or more. In the optical laminate, the polarizer and the adhesive layer may be arranged in this order on a first principal surface of the glass layer. A transparent film may be disposed between the glass layer and the polarizer.
