Abstract

An array substrate, a display panel and a method of manufacturing an array substrate are disclosed. The array substrate includes: a base substrate and a thin film transistor layer disposed on the base substrate. The thin film transistor layer includes an active layer, and further includes a shielding layer that is disposed between the base substrate and the thin film transistor layer and that defines a groove, where the active layer at least partially extends into the groove. In the present application, the problem of leakage current caused by the active layer being exposed to light is improved by the above solution.
