Abstract
A laminated structure includes a polymer layer comprising at least one layer, a gas barrier layer which has thermal resistance of greater than or equal to about 650 degrees Kelvin per watt and a Young's modulus of greater than or equal to about 100 gigapascals, and a position of a neutral axis represented by the following Equation 1 is in the gas barrier layer.In Equation 1, y denotes a distance from the top surface of a side compressed in bending to the neutral axis, Ei denotes a Young's modulus of the i-th layer, Si denotes a geometrical moment of area of the i-th layer, Ai denotes a cross-sectional area of the i-th layer, and n denotes a number of layers for the laminated structure, which is an integer of greater than or equal to 5.
