摘要:
An LCD having a plurality of test pads applied with a common voltage, covered with respective shielding conductor or located sufficiently far from pixels. A gate wire including pluralities of gate lines and test pads disconnected from the gate lines and located near one ends of the gate lines, and a common electrode wire including a plurality of common electrodes and a common electrode pad connected to the common electrode electrodes are formed on a substrate, and covered with a gate insulating film. A data wire and a pixel electrode wire are formed thereon and covered with a passivation film. The passivation film and the gate insulating film have contact holes exposing the test pads and the common electrode pad. A plurality of connecting members which are connected to the test pads and the common electrode pad through the contact holes are formed on the passivation film. Alternatively, the passivation film and the gate insulating layer have contact holes exposing only the common electrode pad, and a plurality of shielding members are provided on the passivation layer to be connected to the common electrode pad and to cover the test pads. Alternatively, the distance between the gate lines and the test pads is equal to or larger than twice the width of the pixel.

In a method of fabricating a thin film transistor array substrate for a liquid crystal display, a gate line assembly is formed on a substrate with a chrome-based under-layer and an aluminum alloy-based over-layer while proceeding in the horizontal direction. The gate line assembly has gate lines, and gate electrodes, and gate pads. A gate insulating layer is deposited onto the insulating substrate such that the gate insulating layer covers the gate line assembly. A semiconductor layer and an ohmic contact layer are sequentially formed on the gate insulating layer. A data line assembly is formed on the ohmic contact layer with a chrome-based under-layer and an aluminum alloy-based over-layer. The data line assembly has data lines crossing over the gate lines, source electrodes, drain electrodes, and data pads. A protective layer is deposited onto the substrate, and patterned to thereby form contact holes exposing the drain electrodes, the gate pads, and the data pads. The sidewall of the under-layers for the gate line assembly and the data line assembly is exposed through the contact holes. An IZO-based layer is deposited onto the substrate, and patterned to thereby form pixel electrodes, subsidiary gate pads, and subsidiary data pads. The pixel electrodes are connected to the sidewall of the drain electrodes, and the subsidiary gate and data pads are connected to the sidewall of the gate and the data pads.
