Abstract
A liquid crystal display element for matrix display, employing, as address elements, thin film transistors each having a layered arrangement of a gate electrode, an insulating film, a semiconductor film, a source electrode, a drain electrode and a display picture element electrode formed in that order on an insulating substrate. The liquid crystal display element is characterized by a thin metallic film for smoothing path lines for the source electrodes, formed of the same material as that forming the gate electrodes in a plane including the gate electrodes.
