摘要:
A liquid crystal display device (100) according to the present invention includes a plurality of pixels arrayed in a matrix, n number of the pixels (n is an even number of 4 or greater) being included in a color display pixel (CP). The liquid crystal display device includes an active matrix substrate (10) including a plurality of scanning lines (12) extending in a row direction and a plurality of signal lines (13) extending in a column direction; and a signal line driving circuit (3) that supplies, as a display signal, a gray scale voltage of a positive or negative polarity to each of the plurality of signal lines. The plurality of signal lines include a first type of signal line (13a) which does not intersect another signal line, and a second type of signal line (13b) which intersects a signal line adjacent thereto outside a display area in the state where an insulating film (16) is interposed therebetween. The active matrix substrate further includes a correction line (40) which is provided in the vicinity of an intersection region (IR) 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.
