Measures are taken against the problem that a conductive matter is attached to an organic film in the vicinity of terminal sections of a display device, which causes electrical connection between the terminals when the terminals are connected to a flexible wiring board. An organic passivation film is formed to the vicinity of the end of the substrate, and a conductive matter is attached to the edge of the organic passivation film. The conductive attachment is divided by extending a bridge section of the organic passivation film to the end of the substrate. Thus, even if a flexible wiring board is connected thereto, the electrical connection between the terminals can be prevented.
