摘要： 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.

摘要： The liquid crystal display device includes: a TFT substrate including scanning lines extending in a first direction and being arranged in a second direction, video signal lines extending in the second direction and being arranged in the first direction, pixel electrodes arranged in regions surrounded by the scanning lines and the video signal lines, and common electrodes formed with an insulating film arranged between the common electrodes and the pixel electrodes; a counter substrate opposed to the TFT substrate; and a liquid crystal. The first common electrode extends between the first and second scanning lines in the first direction, and the second common electrode extends between the second and third scanning lines in the first direction. The first and second common electrodes are electrically connected by a bridge. The bridge covers the first video signal line without covering the second video signal line, when seen in a plan view.

摘要： A liquid crystal display device includes a TFT substrate and a counter substrate with liquid crystal sandwiched therebetween. 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.

摘要： The invention prevents the display unevenness of a high-resolution liquid crystal display device that results from the presence of regions where an alignment film is not applied. The invention provides a liquid crystal display device including: a TFT substrate having scan lines, video signal lines, and pixels formed by the intersecting scan lines and video signal lines; a counter substrate; and a liquid crystal layer placed between the TFT substrate and the counter substrate. Each of the pixels includes a TFT, a pixel electrode, a common electrode, and a through-hole and an opening that are used to connect the TFT and the pixel electrode. Connective ITO is formed in and around the through-hole at the same time as the common electrode is formed. A step d is formed at an edge portion of the connective ITO and covered with an alignment film.

摘要： 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.
