PROBLEM TO BE SOLVED: To provide a display device excellent in display picture quality, and a method of manufacturing the same. SOLUTION: A scanning line Ls and a source voltage line La (including a power supply wiring layer Lay) each have a wiring structure formed by laminating lower-layer wiring parts Ls0 and La0 and an upper-layer wiring part Especially, the upper-layer wiring part has a wiring structure formed by laminating a low-resistance metal layer (upper-layer side metal thin films Ls2 and La2) for reducing wiring resistance of aluminum alone, aluminum alloy, etc., and a transition metal layer (lower-layer side metal thin films Ls1 and La1) for reducing migration of chromiumi (Cr), titanium (Ti), etc. COPYRIGHT: (C)2008,JPO&INPIT
