Abstract:
1. A liquid crystal display device, comprising: a substrate; a gate electrode disposed on the substrate; a gate pad disposed on the substrate; an insulating film disposed on the gate electrode and the gate pad; an active layer disposed on the insulating film above the gate electrode; an ohmic contact layer disposed on portions of the active layer; a source electrode and a drain electrode disposed on the ohmic contact layer; a passivation layer disposed on the source and drain electrodes; a pixel electrode disposed on the passivation layer and contacting the drain electrode; and a transparent electrode disposed on the passivation layer and contacting the gate pad, wherein the gate electrode and the gate pad both include a first layer formed of a first metal and an alloy layer formed on the surface of the first layer by heat generated by continuously depositing a second metal on the first metal, a residual of the second metal is entirely removed so that the alloy layer of the gate pad is directly connected to the transparent electrode, and wherein the first metal includes aluminum, and the alloy layer includes an alloy of aluminum and the second metal.
