Array substrate, display apparatus having the same and method for repairing the same

A display apparatus comprising:

• the array substrate comprising:
• a substrate comprising a display area and a peripheral area that is adjacent to the display area;
• a first signal line at the peripheral area of the substrate to receive a driving signal;
• a second signal line at the display area, the second signal line being coupled with the first signal line to receive the driving signal;
• a pixel array at the display area to receive the driving signal from the second signal line;
• and
• a crossing part at the peripheral area, the crossing part intersecting and insulated from the first signal line;
• an opposite substrate facing the array substrate;
• and
• a driving part on the array substrate to output a driving signal.

A display apparatus, comprising:

• an array substrate comprising;
• a substrate comprising a display area and a peripheral area that is adjacent to the display area,
• a first gate signal line part provided at the peripheral area to receive the gate signal from the gate driving chip;
• a first data signal line part provided at the peripheral area to receive the data signal from the data driving chip;
• a second gate signal line part provided at the display area, the second gate signal line part being coupled with the first gate signal line part to receive the gate signal from the first gate signal line part;
• a second data signal line part provided at the display area of the substrate, the second data signal line part being coupled with the first data signal line part to receive the data signal from the first data signal line part;
• a gate side repair part to repair a first opened gate signal line;
• a dummy gate side repair part to repair a second opened gate signal line;
• a data side repair part to repair an opened first data signal line part;
• and
• a dummy data side repair part to repair a second opened first data signal line part;
• an opposite substrate corresponding to the array substrate;
• a gate driving chip provided at the array substrate to transmit a gate signal;
• and
• a data driving chip provided at the array substrate to transmit a date signal.

A method for repairing an array substrate, comprising:

• irradiating a first laser beam upon a first overlap portion where a first end portion of an opened signal line overlaps a first repair line to couple the opened signal line with the first repair line;
• irradiating a second laser beam upon a second overlap portion where a second end portion of the opened signal line overlaps a second repair line to couple the opened signal line with the second repair line;
• irradiating a third laser beam upon a third overlap portion where an end portion of the first repair line overlaps a connecting line to couple the first repair line with the connecting line;
• and
• irradiating a fourth laser beam upon a fourth overlap portion where an end portion of the second repair line overlaps the connecting line, to couple the second repair line with the connecting line.
