DISPLAY DEVICE AND METHOD FOR PRODUCING SAME

摘要

A display device is provided with highly reliable wiring. Also provided is a method for producing the display device. First wiring (40) according to the present invention is wiring having a two-layer structure that comprises lower layer wiring (41) and upper layer wiring (42) formed so as to cover the upper surface and both side surfaces of the lower layer wiring. In this way, even when there is a location at which the wiring width becomes thin and begins to break as a result of foreign matter or the like adhering to the lower layer wiring during the formation thereof, the probability that foreign matter will adhere again to the position corresponding to the location at which the lower layer wiring is beginning to break is extremely low during the formation of the upper wiring layer. In addition, the lower layer wiring (41) and the upper layer wiring (42) are electrically connected. As a result, highly reliable wiring is obtained in which the first wiring conducts via the upper layer wiring even when a location at which the lower layer wiring is thin breaks, and it is thus possible for a liquid crystal display device to continue displaying an image in a normal manner.
