Abstract:
1. A method of manufacturing a display panel, comprising: preparing a first substrate; forming a gate line on the first substrate; forming a semiconductor pattern partially overlapped with the gate line; forming a data line on the first substrate to define a pixel area together with the gate line; forming a source electrode branched from the data line in the pixel area; forming a drain electrode spaced apart from the source electrode in the pixel area and the drain electrode comprising a same material as the source electrode; forming a pixel electrode electrically connected to the drain electrode in the pixel area; and combining the first substrate and a second substrate facing the first substrate, wherein the source and drain electrodes are formed by: forming on the first substrate, an aluminum based alloy layer containing a sufficient amount of nickel to substantially inhibit corrosion during dry etching of the aluminum based alloy layer; and
