Abstract:
1. A liquid crystal display device, comprising a plurality of pixels arrayed in a matrix including a plurality of rows and a plurality of columns, n number of the pixels (n is an even number of 4 or greater) being included in each of color display pixels, the liquid crystal display device comprising: an active matrix substrate including a plurality of scanning lines extending in a row direction and a plurality of signal lines extending in a column direction; and a signal line driving circuit that supplies, as a display signal, a gray scale voltage of a positive or negative polarity to each of the plurality of signal lines; wherein: the n number of pixels are arrayed in p rows by q columns (p is an integer of 1 or greater, and q is an even number of n or smaller) in each of the color display pixels; the plurality of signal lines include a first type of signal line which does not intersect another signal line, and a second type of signal line which intersects a signal line adjacent thereto outside a display area in a state where an insulating film is interposed therebetween; the active matrix substrate further includes a correction line which is provided in the vicinity of an intersection region where the second type of signal line intersects the adjacent signal line, is electrically separated from the plurality of signal lines, and is at a floating potential; the correction line is provided so as to partially overlap the second type of signal line as seen in a direction normal to the substrate; the correction line is formed of a conductive film same as that of a part of the plurality of scanning lines which is located in the display area or formed of a conductive film same as that of a part of the plurality of signal lines which is located in the display area; the correction line includes a first correction line portion defined by one of a pair of the second type of signal lines that intersect with each other that is made from a source metal layer and a second correction line portion defined by another one of the pair of the second type of signal lines that intersect with each other that is made from a gate metal layer; each of the plurality of signal lines which is outside of the display area includes a lower layer line made of the gate metal layer and an upper layer line made of the source metal layer; and the first correction line portion partially overlaps the lower layer line and the second correction line portion partially overlaps the upper layer line.
