Abstract
A gas barrier substrate including a flexible base material, at least one first inorganic gas barrier layer and at least one second inorganic gas barrier layer is provided. The flexible base material has an upper surface. The first inorganic gas barrier layer is disposed on the flexible base material and covers the upper surface. The second inorganic gas barrier layer is disposed on the first inorganic gas barrier layer and covers the first inorganic gas barrier layer. A water vapor and oxygen transmission rate of the second inorganic gas barrier layer is lower than that of the first inorganic gas barrier layer.
