A liquid crystal display device has on each pixel region at a liquid-crystal side of one of a pair substrates, a thin film transistor driven by scanning signals from a gate signal line, a pixel electrode to which video signals from a drain signal line are supplied through the thin film transistor, and a capacity element formed between the pixel electrode and a holding capacity electrode. The capacity element is formed such that a semiconductor layer forming the same layer as a semiconductor layer of the thin film transistor, a first insulation film forming the same layer as a gate insulation film of the thin film transistor, the holding capacity electrode, a second insulation film and a metal layer are sequentially. The semiconductor layers and the metal layer are connected to each other. The metal layer is formed as a reflector which occupies a portion of the pixel region.

A method of performing thermal working to metal material containing helium, which comprises the steps of previously feeding current through a thermally working portion of the metal material containing helium to thereby reduce a helium content in the portion without melting the portion and then heating and melting the portion to improve the defects of the metal structure of the metal material containing helium. As a result, the improvement and removal of defects of the metal structure can be achieved by reducing a helium content in the thermally working portion of the metal material.
