Abstract
In a large-sized substrate for use in liquid crystal display devices, microcracks in a gate insulating film are prevented from being generated, whereby warpage of the substrate is suppressed. In order to solve the problems, in thin film transistors arrayed on a glass substrate, the gate insulating film is made thicker only in the portion that is directly under a gate line layer.
