    摘要: A display device including an oxide thin film transistor (TFT) is disclosed. A nitride-based gate insulating layer of a gate pad area is etched when an oxide semiconductor layer of a pixel area is etched by using a half-tone mask, a metal layer is formed at a contact hole of the etched gate insulting layer, and then a passivation layer formed thereon is etched. Thus, an overhang of the passivation layer can be prevented from being generated when the gate insulating layer is etched, and accordingly, the fabrication process can be simplified.

    摘要: Disclosed are a liquid crystal display device employing an amorphous zinc oxide-based semiconductor as an active layer, and a method for fabricating the same, whereby device stability can be secured by employing an etch stopper structure and device characteristics can be enhanced by minimizing exposure and deterioration of the active layer excluding content regions by virtue of the design of the etching stopper in a shape like “H”. Also, the liquid crystal display device and the fabrication method thereof can further form a semiconductor pattern and an insulating layer pattern on the intersection between the gate line and the data line, so as to compensate a stepped portion, thereby preventing an occurrence of short-circuit.
