REPAIR DEVICE OF DISPLAY SUBSTRATE AND REPAIR METHOD OF DISPLAY SUBSTRATE

摘要

A device and a method for repairing a display substrate are provided to remove impurities generated around a patterning fault part during a repairing process using a laser beam as soon as the impurities are generated, thereby reducing a fault rate of the display substrate caused by remaining impurities. A laser irradiating unit(10) is disposed on a patterning fault part(43), and repairs patterning faults by irradiating a laser beam to the patterning fault part. A gas supply unit(20) is disposed so as to be adjacent to the laser irradiating unit, and forms airflow of a constant direction by supplying gas to the patterning fault unit. The gas supply unit moves impurities, generated on the patterning fault part during the repairing process, along the airflow. A suction unit(30) is disposed so as to be adjacent to the patterning fault part and sucks the impurities moving along the airflow.
