Abstract: The present application discloses a thin film transistor and an array substrate. The thin film transistor includes a gate electrode, a source electrode, and a drain electrode, and at least one of the gate electrode, the source electrode, or the drain electrode is a composite film layer. The composite film layer includes a metal layer, a low reflection functional layer, and an alloy layer which are arranged in layers.
