Display device having repair and detect structure comprising an isolation layer placed between the repair segment and shorting segment

A display device having repair and detect structure, comprising:

• a substrate;
• a pixel array disposed on the substrate, the pixel array comprising a plurality of data lines and a plurality of gate lines, wherein the substrate comprises a first peripheral region and a second peripheral region defined outside the pixel array, the first peripheral region is arranged parallel to the gate lines, the second peripheral region is arranged parallel to the data lines;
• a first shorting bar disposed on the substrate, the first shorting bar being connected to the gate lines for testing the gate lines, and the first shorting bar comprising a first shorting segment placed along a first direction;
• a first repair line disposed on the substrate for repairing at least one of the data lines, the first repair line comprising a first repair segment placed along the first direction, and the first repair segment overlapping with the first shorting segment in the first peripheral region;
• a second shorting bar and a second repair line disposed on the substrate, wherein the second shorting bar comprises a second shorting segment, the second shorting segment is placed along the first direction, the second repair line comprises a second repair segment placed along the first direction, and the second repair segment overlaps with the second shorting segment in the first peripheral region;
• a repair line branch disposed in the first peripheral region, wherein one end of the repair line branch is electrically connected to the first repair line, and the other end of the repair line branch is electrically connected to the second repair line;
• and
• an isolation layer placed between the first repair segment and the first shorting segment.
