Patent ID: 8890139

Claim:
A thin film transistor array panel comprising: a substrate; a gate line, a semiconductor layer, a source electrode, a data line, and a drain electrode disposed on the substrate; and a passivation layer disposed on the gate line, the semiconductor layer, and the data line, wherein the semiconductor layer is in direct contact with the passivation layer, the passivation layer including an organic siloxane resin represented by Chemical Formula 1 below: wherein in Chemical Formula 1, R is at least one substituent selected from the group consisting of a saturated hydrocarbon or an unsaturated hydrocarbon having from 1 to about 25 carbon atoms, and x and y are each independently an integer from 1 to about 200, wherein each wavy line indicates a bond to an H atom or to an x siloxane unit or a y siloxane unit, or a bond to an x siloxane unit or a y siloxane unit of another siloxane chain comprising x siloxane units or y siloxane units or a combination thereof.
