Abstract

A method of repairing a display panel comprising: determining a pixel where a bright spot defect resides and a position of the bright spot in the pixel; setting a repair region, the repair region being a region in the pixel including the bright spot defect and having an area smaller than that of a single pixel region; forming a black material layer in the repair region, the black material layer being used for preventing light emitted from a directly-below portion thereof from leaving a display surface of the display panel.
