A flexible substrate is disclosed. The flexible substrate includes a polymer substrate and a plurality of water and oxygen barrier layers provided on the polymer substrate, where a planarization layer is provided between the adjacent water and oxygen barrier layers, the planarization layer includes a plurality of planarization units separated in a first direction and a second direction, a projection of the planarization unit in the planarization layer projected on the polymer substrate covers a gap between projections of adjacent planarization units in an adjacent planarization layer projected on the polymer substrate, and projection regions partially overlap. In this way, the adjacent planarization layers can cover the gap between the planarization units to prevent the water and oxygen horizontal from penetrating to ensure that the flexible substrate can be cut into any size within the range lager than the size of the planarization unit. |
