Patent ID: 8610127

Claim:
A thin film transistor array substrate comprising: gate lines and data lines formed to cross each other in the center of a gate insulation film on a substrate and to define pixel regions; a thin film transistor formed at each intersection of the gate and data lines; a passivation film formed on the thin film transistors; a pixel electrode formed on each of the pixel regions and connected to the thin film transistor through the passivation film; a gate pad connected to each of the gate lines through a gate linker; and a data pad connected to each of the data lines through a data linker, wherein the data pad is formed of a gate pattern, the data line is formed of a data pattern, the data linker is configured to connect the data pad formed of the gate pattern with the data line formed of the data pattern using a connection wiring and include the gate pattern connected to the data pad, the data pattern formed opposite to the gate pattern in the center of the gate insulation film, and the connection wiring configured to connect the gate pattern with the data pattern through a first contact hole which exposes the data pattern and the gate pattern by penetrating through the passivation film and the gate insulation film, wherein the whole of the data pattern is overlapped with a part of the gate pattern, wherein the first contact hole is formed in a center area of the gate pattern, and wherein the thin film transistor is configured to include a gate electrode connected to the gate line, a source electrode connected to the data line, and a drain electrode connected to the pixel electrode, an active layer which is disposed to overlap with the gate electrode in the center of the gate insulation layer and to form a channel between the source and drain electrodes.
