ELECTRONIC CIRCUIT SUBSTRATE, ITS MANUFACTURING METHOD, AND DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a flexible substrate high in connection reliability and capable of preventing disconnection defects from occurring even if repeatedly bent, its manufacturing method, and a display device using the substrate. SOLUTION: The flexible device is composed so that at least a part of a metal wiring 12 formed on the substrate is covered with a conductive polymer. Concretely, the metal wiring 12 is formed on the substrate 11. A conductive polymer wiring 13 is formed so as to cover a part on the wiring. The metal wiring 12 and the conductive polymer wiring 13 are made into a multi-layer structure. COPYRIGHT: (C)2006,JPO&NCIPI
