Abstract
An array substrate, a manufacturing method thereof, and a display device are provided. The array substrate includes: a base substrate; a first signal line on the base substrate; a first buffer layer provided on the base substrate and covering the first signal line; a second signal line on a side of the first buffer layer facing away from the base substrate; a first insulating layer provided on the base substrate and covering the second signal line; and a thin film transistor on a side of the first insulating layer facing away from the base substrate, the thin film transistor including a gate electrode, a source electrode and a drain electrode. A thickness of the first signal line is greater than that of the gate electrode, and a thickness of the second signal line is greater than that of the source electrode or the drain electrode.
