    摘要: A liquid crystal display device includes transparent pixel electrodes disposed at intersections of scanning signal lines and data lines, and a plurality of thin film transistors each of which is provided correspondingly to one of the pixel electrodes. Each of the transistors includes an output electrode connected to one of the pixel electrodes, a control electrode connected to one of the scanning signal lines, and an input electrode connected to one of the data lines. A first insulating film covers the scanning signal lines, and a semiconductor layer is interposed between the first insulating film and a portion of the data lines. The method of making the liquid crystal display device includes the steps of etching a transistor semiconductor layer underlying the output electrode, in the thin film transistors using a photoresist mask formed on the transistor semiconductor layer such that an etched end of the transistor semiconductor layer on a side of the output electrode extends beyond an end of the output electrode, and etching an end of the semiconductor layer underlying the data lines, of the semiconductor layer using a metal film making up the data lines as a mask.

    摘要: In a liquid crystal display device having a terminal or the like in a periphery thereof which has a conductive layer extending along a certain direction thereof and being covered with an insulating film and an oxide conductor layer formed on the insulating layer and contacting with the conductive layer in an opening in the insulating film, arrangements are provided to prevent disconnection of the oxide conductor layer. A semiconductor layer is provided under the conductive layer to be extending therealong in the liquid crystal display device. The semiconductor layer is also formed to be extended beyond an end of the conductive layer or to be wider than the conductive layer around the opening in the insulating film in the periphery of the liquid crystal display device.
