PROBLEM TO BE SOLVED: To include a glass layer and to improve flexibility by a method in which the first and second layers are included, the first layer is a glass layer, and a crack line is formed in the glass layer. SOLUTION: A laminate 50 includes a glass layer 10, the second layer 20, and an additional glass layer, the glass layer 10 is laminated on the surface 21 of the second layer 20, and the additional glass layer 40 is laminated on the surface 24 opposite to the surface 21 of the second layer 20. Crack lines 11, 41 are formed in the glass layer and the additional glass layer 40, respectively. The crack lines are arranged in a hexagonal pattern and have a depth equal to the thickness of each glass layer. When the laminate is deformed, in the glass layers, each hexagon can move around the crack line. Especially, when a hexagonal elements are small enough, the flexibility of the laminate is determined chiefly by the flexibility of the second layer 20 which is a polymer layer and others. The laminate 50 having good flexibility can be obtained by this method. |
