Abstract
A manufacturing method of a liquid crystal display of the present invention is a manufacturing method of a liquid crystal display having a glass substrate provided thereon with a matrix of thin film transistors, each having a semiconductor film pattern formed by photo-etching a high-resistance semiconductor film and a low-resistance semiconductor film, and a third metal film serving as a source metal film layer layered on the semiconductor film pattern, in which the semiconductor film pattern is formed on the glass substrate first, and thence the third metal film is layered on the glass substrate. Consequently, a liquid crystal display can be manufactured with a fewer number of manufacturing steps while at the same time the manufacturing costs can be saved by preventing a decrease in the yield caused by film separation.
