Abstract

A liquid crystal display device includes a TFT substrate and a counter substrate with liquid crystal sandwiched therebetween. The TFT substrate has scanning linesextending in a first direction and arrayed in a second direction and video signal linesextending in the second direction and arrayed in the first direction. The TFT substrate has a display areain which TFT pixels are arrayed in a matrix pattern, and a frame areasurrounding the display area. In the frame area, common bus wiresare formed in the same layer and with the same material as the video signal linesand are impressed with a common voltage. Dummy TFTs are formed in a layer under the common bus wires. The scanning lines, extending over the frame area, are divided outside the display area and are interconnected by bridging wires
