发明名称 Liquid crystal display including conductive layer passing through multiple layers and method of manufacturing same
摘要 An LCD is adapted to be manufactured using a significantly reduced number of masks and masking processes. In order to form a gate of the LCD, aluminum and one of molybdenum, tantalum, tungsten and antimony are sequentially deposited and patterned using a single mask. Cutting a shorting bar for preventing static electricity is performed while a passivation layer is patterned and rinsed. Accordingly, an LCD produced by this method includes a first metal layer, which includes a first contact hole and is disposed on a substrate, a second metal layer which covers the first metal layer and includes a second contact hole which is smaller than the first contact hole, an insulating layer, which covers the second metal layer and includes a third contact hole larger than the second contact hole, and a pad, which includes a conductive layer contacting the second metal layer through the third contact hole on the insulating layer.
