LIQUID CRYSTAL DISPLAY DEVICE AND DISPLAY DEFECT CORRECTION METHOD

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.
