Display panel and manufacturing method thereof

摘要

A display panel including an array substrate and a COF substrate is provided. The COF is provided with a plurality of welded lead lines. The array substrate includes a metal layer disposed on a surface of the substrate, a silicon nitride layer disposed on a surface of the metal layer, and a plurality of terminal wires disposed in a spaced arrangement in a welding region on a surface of the second silicon nitride layer. The welding region between the adjacent terminal wires is provided with through holes, which expose the metal layer. The risk of corrosion and breakage of the welded lead lines on the COF substrate is effectively reduced.
