Transparent thin film having conductive and nonconductive portions, method of patterning the portions, thin-film transistor array substrate including the thin film and method of manufacturing the same

A method of forming a patterned thin film, the method comprising:

• forming on a substrate, a homogenous and transparent thin film layer having conductive fine-wires mixed with a liquid polymer precursor composition;
• forming a light blocking and patterned mask that protects at least a first area of the transparent thin layer from exposure to a precursor curing light;
• irradiating a precursor curing light onto a second portion of the transparent thin layer not protected by the patterned mask;
• and
• selectively removing from the exposed transparent thin layer, the uncured mixture of conductive fine-wires and the polymer precursor composition of the second area.

A thin-film transistor array substrate comprising:

• a gate line formed on a base substrate;
• a data line extended in a direction crossing the gate line;
• a thin-film transistor connected to the gate line and the data line;
• and
• a pixel electrode including:
• a transparent electrode pattern formed in a layer and having conductive fine-wires;
• and
• a non-conductive sub-portion disposed in the same layer as the transparent electrode pattern, the non-conductive sub-portion including at least one member selected from the group of non-conductive fine-wires consisting of oxidized fine-wires, chloridated fine-wires or fluoridated fine-wires.

A method of manufacturing thin-film transistor substrate, the method comprising:

• forming a gate line, a data line and a thin-film transistor on a base substrate, the data line being extended in a direction crossing the gate line, the thin-film transistor being connected to the data line and the gate line;
• forming on the base substrate having the formed thin-film transistor, a homogenous transparent thin film layer having a mixture of conductive fine-wires and a liquid polymer precursor composition;
• forming a photo pattern over the transparent thin film layer where the photo pattern blocks a supplied curing light from reaching a first area of the transparent thin film layer and allows the supplied curing light to reach a second area of the transparent thin film layer;
• irradiating a curing light through the photo pattern and onto the exposed second area of the transparent thin film layer;
• and
• selectively removing from the irradiated transparent thin film layer, the uncured mixture of conductive fine-wires and the polymer precursor composition of the second area fine-wires.
