Abstract: 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.

Abstract: In a display device having a video signal drive circuit disposed laterally adjacent to the screen, the frame area is reduced and the vertical line noise at the center of the screen is prevented from appearing. Driver lines are drawn to areas disposed above and below a display area from the video signal drive circuit. R, G, and B drain lines are branched from each of the driver lines via R, G, and B switches. The R, G, and B switches are driven by R, G, and B switching lines. In order for preventing the interference between the driver line for supplying the center area of the screen with the image signals and the B switching line, a shield line is disposed between the driver line and the B switching line.
