Abstract:
1. An array substrate for a liquid crystal display (LCD), comprising: a substrate, comprising: a gate pad formed on a gate pad area of the substrate, such that the gate pad is disposed in a same layer as the gate electrode, the gate pad being connected to the gate electrode; a gate insulating layer covering the gate pad and the gate electrode; a first protective layer formed on the gate insulating layer; a second protective layer formed on the first protective layer; a first metal layer formed on the second protective layer corresponding to the gate pad area, and connected to the gate pad through a first contact hole which exposes the gate pad; a third protective layer covering the pixel electrode, the first metal layer, and the second protective layer; and a second metal layer formed on the third protective layer corresponding to the gate pad area, and connected to the first metal layer through a second contact hole which exposes the first metal layer, wherein the first metal layer is formed on a same plane as the pixel electrode, and wherein the second metal layer is formed on a same plane as the common electrode.
