Abstract: A thin-film transistor substrate includes a base substrate, a gate line, a data line, a thin-film transistor, an organic insulating pattern and a common electrode. The base substrate includes a plurality of pixel areas. The gate line is disposed on the base substrate, and the gate line is extended in a first direction. The data line is disposed on the gate line, and the data line is extended in a second direction crossing the first direction. The thin-film transistor is connected to the gate line and the data line. The organic insulating pattern covers the data line and the thin-film transistor, and the organic insulating pattern includes an opening overlapping with the pixel areas. The common electrode is disposed on the base substrate. Thus, an organic insulating layer in a pixel area may be partially removed, so that a yellowish screen may be prevented, thereto improve a display quality. In addition, an organic insulating pattern may be formed on a data pattern, a coupling capacitance between the data pattern and a common electrode may be prevented or decreased, thereto prevent a data signal delay.

Abstract: A method for forming a thin film according to an exemplary embodiment of the present invention includes forming the thin film at a power density in the range of approximately 1.5 to approximately 3 W/cm2 and at a pressure of an inert gas that is in the range of approximately 0.2 to approximately 0.3 Pa. This process results in an amorphous metal thin film barrier layer that prevents undesired diffusion from adjacent layers, even when this barrier layer is thinner than many conventional barrier layers.
