THIN FILM TRANSISTOR, THE METHOD FOR USING THE SAME AND ORGANIC LIGHT EMITTING DISPLAY DEVICE COMPRISING THE TFT

摘要

PURPOSE: A thin film transistor, a method for manufacturing the same, and an organic electroluminescent display device are provided to reduce a defect due to arc by crystallizing an amorphous silicon layer by applying an electric field for a source/drain electrode. CONSTITUTION: A buffer layer(110) is positioned on a substrate(100). A semiconductor layer(120) is positioned on the buffer layer. A gate insulation layer(130) is positioned on the semiconductor layer. A gate electrode(140) is positioned on the gate insulation layer. An interlayer insulation layer(150) is positioned on the substrate including the gate electrode and includes a first contact hole and a second contact hole. A source/drain electrode is positioned on the interlayer insulation layer, is insulated from the gate electrode, and is partially connected to the semiconductor layer through a first contact hole.
