The TFT substrate has scanning lines 10 extending in a first direction and arrayed in a second direction and video signal lines 20 extending in the second direction and arrayed in the first direction. The TFT substrate has a display area 500 in which TFT pixels are arrayed in a matrix pattern, and a frame area 600 surrounding the display area. In the frame area 600, common bus wires 521 are formed in the same layer and with the same material as the video signal lines 20 and are impressed with a common voltage. Dummy TFTs are formed in a layer under the common bus wires 521. The scanning lines 10, extending over the frame area 600, are divided outside the display area and are interconnected by bridging wires 170.

Abstract: The displacement between a TFT substrate and a counter substrate and the cut of an alignment film caused by a columnar spacer are prevented. A liquid crystal display device includes: a TFT substrate including a scanning line extending in a first direction, a picture signal line extending in a second direction, a pixel electrode formed in a region surrounded by the scanning line and the picture signal line, and a common electrode formed as opposed to the pixel electrode through an insulating film; a counter substrate disposed as opposed to the TFT substrate and having a spacer; and a liquid crystal sandwiched between the substrates. A common metal interconnection is formed to cover the picture signal line or the scanning line, and stacked on the common electrode. A through hole is formed on the common metal interconnection. The tip end of the spacer is disposed inside the through hole.

Abstract: A display device is provided with a pixel and a dummy pixel including a gate line and a signal line. The dummy pixel includes the gate line and a dummy semiconductor layer crossing the gate line through an insulating layer. The dummy semiconductor layer is electrically separated from the dummy semiconductor layer of the dummy pixel adjacent in the Y direction dummy pixel. The dummy pixel further includes a dummy signal line extending in the Y direction. The dummy signal line is connected to the dummy semiconductor layer through a plurality of contact holes. The contact holes are arranged with the gate line interposed between them in plan view.
