Abstract
There is disclosed a method for manufacturing an Electro Static Discharge (ESD) device, an ESD device and a display panel, which are capable of addressing an issue that static-electric charges accumulated on the array substrate damage the unformed ESD device and improving a yield ratio of the array substrate. The method includes forming a TFT, a first lead wire, wherein the first lead wire or the second lead wire comprises at least two separate lead-wire segments; depositing a layer of passivation thin film, and forming via-holes for connecting the at least two separate lead-wire segments on the layer of passivation thin film; depositing a layer of transparent conductive film on the substrate on which the via-holes are formed, wherein the layer of transparent conductive film connects the lead-wire segments by the via-holes.
