Panel assembly for display device, display device including the same, and repairing method for display device

A panel assembly for display device, comprising:

• a plurality of data lines for transmitting data voltages;
• a plurality of data driving IC regions where data driving ICs for generating the data voltages and applying the data voltages to the data lines are disposed;
• and
• a plurality of auxiliary repair lines which are formed in the data driving ICs and are disposed asymmetrically at both sides of the data lines.

A repairing method for a display device which comprises:

• a plurality of data lines for transmitting data voltages;
• a plurality of repair lines which intersect the data lines;
• and a plurality of auxiliary repair lines which are formed in a plurality of predetermined regions and disposed at both sides of the data lines, wherein at least some portions thereof intersect the repair lines, the repairing method comprising steps of
• testing the data lines,
• connecting the data lines with at least one of the repair lines,
• connecting the repair lines connected to the data lines with at least one of the auxiliary repair lines, and
• applying a repair checking signal through the connected auxiliary repair line.
