Abstract
The present invention provides a piezoelectric transformer, a piezoelectric inverter, and a liquid crystal display with a high reliability, capable of preventing the occurrence of the soundings caused by the contact between gold thread wires and preventing the breaking of the gold thread wires and the deterioration of the performance of the piezoelectric transformer. The gold thread wire for wiring used in a piezoelectric transformer has a structure wherein band-like metallic foils are wound around a core consisting of numerous fine wires bundled, and the gold thread wire is constituted by impregnating it with wax.
