Abstract: Provided are an array substrate, a display panel, a display apparatus and a method for manufacturing an array substrate. The array substrate includes: a base substrate; an active layer, which is located on one side of the base substrate, where the active layer includes a channel region, a conductive source region, which is located on one side of the channel region, and a conductive drain region, which is located on the other side of the channel region; and a metal layer, which is located on the side of the active layer that is away from the base substrate, where the metal layer includes a gate electrode and a signal line, which are arranged on the same layer, and the thickness of the gate electrode perpendicular to the base substrate is less than the thickness of the signal line perpendicular to the base substrate.
