LIQUID CRYSTAL DISPLAY DEVICE DISPLAY DEFECT CORRECTION METHOD Russian patent published in 2014 - IPC G02F1/1345 

FIELD: physics.

SUBSTANCE: display device has an active matrix substrate, having a plurality of scanning lines which run in a row direction, a plurality of signal lines (13) which run in a column direction and a signal line control circuit which applies voltage as a display signal on each of the signal lines. The plurality of signal lines include a first type of signal line (13a) which does not cross another signal line, and a second type of signal line (13b) which crosses an adjacent signal line on an insulating film outside the display region. The active matrix substrate further includes a correction line (40) which is electrically separated from the plurality of signal lines and has a floating potential in the vicinity of the region (IR) of intersection, where the second type of signal line crosses an adjacent signal line.

EFFECT: improved device.
