摘要： A substrate (01) includes: a base substrate (7), a thin film transistor (16) disposed on the base substrate (7), an organic insulating layer (11) and an inorganic passivation layer (10) which are disposed on the thin film transistor (16) in sequence; and at least a portion of the organic insulating layer (11) which is in contact with the inorganic passivation layer (10) is provided with a concave-convex structure. The contact area of the organic insulating layer (11) and the inorganic passivation layer (10) is increased by the concave-convex structure, thereby the internal stress of the inorganic passivation layer (10) which is easy to cause cracks of the inorganic passivation layer (10) is released, and further the phenomenon that the inorganic passivation layer (10) falls off is reduced or eliminated.
