Display device and repairing method for the same

A repairing method for a display device, the display device comprising a pixel array, at least one gate driver unit, and at least one source driver unit, the pixel array comprising a plurality of gate lines and a plurality of source lines, one of the source lines being divided into a first source line section and a second source line section, the first source line section and the second source line section being discrete, and the first source line section electrically connected to the at least one source driver unit, the repairing method comprising the following steps:

• providing a first repair line disposed between the pixel array and the at least one source driver unit, a second repair line disposed opposite to the first repair line on the pixel array, a first dummy line disposed at one side of the pixel array, and a second dummy line disposed opposite to the first dummy line on the pixel array, the first repair line crossing the source lines and in an initial state being electrically insulated from the source lines, the second repair line crossing the source lines and in an initial state being electrically insulated from the source lines, the first dummy line crossing the gate lines, the first repair line, and the second repair line, the first dummy line in an initial state being electrically insulated from the gate lines, the first repair line, and the second repair line, the second dummy line crossing the gate lines, the first repair line, and the second repair line, and the second dummy line in an initial state being insulated from the gate lines, the first repair line, and the second repair line, and the first dummy line and the second dummy line being not electrically connected to pixels of the pixel array;
• electrically connecting the first source line section to the first repair line;
• electrically connecting the second source line section to the second repair line;
• electrically connecting both of the first repair line and the second repair line to either the first dummy line or the second dummy line;
• and
• cutting the first repair line and the second repair line to electrically connect the first source line section to the second source line section via a portion of the first repair line, either the first dummy line or the second dummy line, and a portion of the second repair line.
