Display panel, methods of fabricating and repairing the same

A method of repairing an electrical short circuit between a data line and a common electrode layer in a display panel, wherein the display panel comprises:

• an array substrate and an opposing substrate facing the array substrate;
• a data line layer comprising a plurality of data lines on the array substrate;
• a passivation layer on a side of the data line layer closer to the opposing substrate;
• a sealant layer on a side of the passivation layer away from the data line layer, sealing the array substrate and the opposing substrate together;
• the display panel comprising a first area enclosed by the sealant layer and a second area outside of the first area and the sealant layer;
• the plurality of data lines extending from the first area into the second area;
• and
• a common electrode layer on a side of the sealant layer away from the passivation layer, the common electrode layer being in the opposing substrate;
• wherein the common electrode layer comprises a portion having a plurality of connections, and a plurality of slits spaced apart from each other by the plurality of connections;
• the plurality of slits and the plurality of connections extending from the first area into the second area, a respective one of the plurality of connections is between two adjacent slits;
• the respective one of the plurality of connections has a first portion in the first area and a second portion in the second area;
• the plurality of connections are directly electrically interconnected in the first area;
• and
• the plurality of connection are directly electrically interconnected in the second area;
• the method comprising:
• identifying the data line involved in the electrical short circuit;
• identifying a connection in the display panel from an area corresponding to the data line in plan view of the display panel;
• and
• insulating the connection from the common electrode layer by disconnecting the connection from the common electrode layer at both the first portion and the second portion.
