  • Display panel and display device
    Patent number: 12048210
    Abstract: A display panel includes a substrate, a plurality of data lines, at least one circle of barrier wall structure, and a connector. The substrate includes a display area, and a peripheral area which surrounds the display area and includes a fan-out area. The plurality of data lines are located on one side of the substrate and in the display area, extending from the display area to the fan-out area. The at least one circle of barrier wall structure surrounds the display area, and at least a part of the at least one circle of barrier wall structure is located in the fan-out area. The connector is located between the plurality of data lines and the barrier wall structure, and one end, away from the substrate, of the connector extends into the barrier wall structure to fasten the barrier wall structure.
