Abstract
A liquid crystal display apparatus has a display region in the substrate and a peripheral circuit region for driving the display region formed in the periphery, and monopolar thin film semiconductor elements and bipolar thin film semiconductor elements are formed in the peripheral circuit region and monopolar thin film semiconductor elements or bipolar thin film semiconductor elements are formed in the display region. In the semiconductor film of the monopolar semiconductor element and the bipolar semiconductor element, both of a zone containing a high concentration n-type impurity and a zone containing a high concentration p-type impurity are formed. The liquid crystal display apparatus consumes a small amount of electric power.
