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

摘要

A display device having repair and detect structure includes a substrate, a pixel array, a first shorting bar and a first repair line. The pixel array disposed on the substrate includes a plurality of data lines and a plurality of gate lines. The first shorting bar disposed on the substrate is connected to the gate lines for testing the gate lines, and the first shorting bar includes a first shorting segment. The first repair line is disposed on the substrate for repairing at least one of the data lines. The first shorting segment of the first shorting bar is electrically connected to the first repair line. Furthermore, another repair and detect structure of a display device is disclosed, wherein the first shorting bar includes a first shorting segment, the first repair line includes a first repair segment, and the first shorting segment overlaps with the first repair segment.
