Abstract
Abstract An electrical device including a glass substrate, an intrgrated circuit chip, an electrical device and electrical conductor paths applied to the surface of the glass substrate and connected to electrical terminals of the integrated circuit chip and the electrical device. The conductor paths are divided into supply conductor paths for supplying voltage to the integrated circuit chip and actuation conductor paths for actuating the electronic device. The actuation conductor paths are composed of layers of indium tin oxide deposited on the glass surface and the supply conductor paths are composed of metal films glued on the glass surface.
