Array substrate and display panel

The embodiment of the invention discloses an array substrate and a flexible display panel. The array substrate comprises a flexible substrate, a thin film transistor (TFT), a first metal layer, a second metal layer and a stacking structure, wherein the stacking structure comprises multiple layers of inorganic layers, the thin film transistor comprises a source electrode, a drain electrode, a channel and a grid electrode isolated from the source electrode, the channel and the drain electrode, the multiple layers of inorganic layers comprise one or more layers of buffering layers located between the flexible substrate and the thin film transistor, one or more layers of grid insulating layers located between the channel and the grid electrode, and a first isolating layer located between the TFT and the second metal layer, and at least one inorganic layer of the multiple layers of inorganic layers is provided with multiple openings at the position corresponding to a display area, so that the problem that normal w
