    摘要: A method of manufacturing a display substrate includes forming a first metallic pattern including gate and storage conductors and a gate electrode of a switching device on a base substrate, forming a gate insulation layer, forming a second metallic pattern and a channel portion including a source line, source and drain electrodes of the switching device, forming a passivation layer and a photoresist film on the second metallic pattern, patterning the photoresist film to form a first pattern portion corresponding to the gate and source conductors and the switching device, and a second pattern portion formed on the storage line, etching the passivation layer and the gate insulation layer, and forming a pixel electrode using the first pattern portion. Therefore, excessive etching of the stepped portion may be prevented, so that a short-circuit defect between a metallic pattern and a pixel electrode may be prevented

    摘要: A thin film transistor includes a gate electrode on a substrate, a gate insulating layer on the substrate, a channel pattern, a source electrode and a drain electrode. The channel pattern includes a semiconductor pattern formed on the gate electrode and overlaying the gate electrode as well as first and second conductive adhesive patterns formed on the semiconductor pattern and spaced apart from each other. The source electrode includes a first barrier pattern, a source pattern and a first capping pattern sequentially formed on the first conductive adhesive pattern. The drain electrode includes a second barrier pattern, a drain pattern and a second capping pattern sequentially formed on the second conductive adhesive pattern. Etched portions of the first and second conductive adhesive patterns have a substantially vertical profile to prevent the exposure of the source and drain electrodes, thereby improving the characteristics of the thin film transistor.
