The embodiment of the invention discloses an array substrate and a display panel. The array substrate comprises a substrate, a first inorganic layer arranged on the substrate and a plurality of thin film transistors arranged on the first inorganic layer, wherein each thin film transistor comprises a second inorganic layer and a third inorganic layer which are arranged in a laminated manner; at least one first groove running through the first inorganic layer and the second inorganic layers between every two adjacent thin film transistors; at least one second groove running through the third inorganic layer is arranged between each thin film transistor and the first groove; a first organic layer is arranged between the first groove and the second groove on the same side of the thin film transistors, on the side, away from the substrate, of the first inorganic layer, on the side, away from the first inorganic layer, of the second inorganic layer, or on the same side of the thin film transistors arranged on the substrate; and the first organic layer and the first groove are covered with the third inorganic layer. According to the array substrate and the display panel provided by the invention, the suffered stress of the display panel during bending can be reduced.
