A display panel includes a base substrate including a first surface; another base substrate including a second surface disposed face the first surface; a first insulating layer disposed above the first surface of the base substrate, a plurality of grooves being disposed in a surface of the first insulating layer away from the base substrate; a first conductive layer disposed at a side of the first insulating layer away from the base substrate, the first conductive layer at least covering bottom faces and side walls of the plurality of grooves; a plurality of support portions disposed above the second surface of the another base substrate; and a second conductive layer disposed at a side of the plurality of support portions away from the another base substrate, the second conductive layer at least covering surfaces of the plurality of support portions facing away from the another base substrate and side faces of the plurality of support portions. Each support portion is embedded into a respective one of the plurality of grooves, and the first conductive layer is in electrical contact with the second conductive layer at the bottom faces and side walls of the plurality of grooves.
