Disclosed is a flexible substrate, comprising a first organic layer, a first inorganic layer, a second organic layer and a second inorganic layer. The first inorganic layer is located on the first organic layer. The first inorganic layer comprises first strips which are spaced. The first strip comprises a first middle part and two first side parts. The second organic layer covers the first inorganic layer. The second inorganic layer is located on one side of the second organic layer remote from the first organic layer. The second inorganic layer comprises second strips which are spaced. The second strip comprises a second middle part and two second side parts. An extension direction of the second strips is the same as an extension direction of the first strips, the second organic layer is partially interposed between two first strips and between two second strips which are adjacent.
