US 2014/0209915 A1 · THIN FILM TRANSISTOR ARRAY PANEL AND MANUFACTURING METHOD THEREOF

Abstract

A thin film transistor (TFT) array panel and a manufacturing method thereof are disclosed. A contact hole may be formed to expose a pad disposed on a substrate of the TFT array panel. A first layer of a connecting member is formed with the same layer as a first field generating electrode and is disposed in the contact hole. A second passivation layer is disposed in the TFT array panel, but is removed at a region where the contact hole is formed and portions of the second passivation layer that cover the first layer of the connecting member. A second layer of the connecting member is formed on the first layer of the connecting member.
