Abstract
In a liquid crystal display apparatus including a gate electrode formed on an insulating layer a gate insulating layer formed on the gate electrode, and a semiconductor active layer formed on the gate insulating layer, a source electrode and a drain electrode are formed on the semiconductor active layer, and have a double structure including a first conductive layer and a second conductive layer formed on the first conductive layer. Also, a pixel electrode is formed on an insulating layer and is connected to the second conductive layer of the drain electrode via a contact hole perforated in the insulating layer. The pixel electrode is made of the same material as that of the second conductive layer.
