Abstract: A backplane, a backlight source, an illumination device and a displaying device. The backplane comprises a substrate; a first metal trace layer disposed on one surface of the substrate; an insulating layer disposed on a side, away from the substrate, of the first metal trace layer; a second metal trace layer disposed on a side, away from the substrate, of the insulating layer, an overlapping area existing between an orthographic projection of the second metal trace layer on the substrate and an orthographic projection of the first metal trace layer on the substrate; and a barrier layer disposed between the first metal trace layer and the second metal trace layer, an orthographic projection of the barrier layer on the substrate covering the overlapping area, and the barrier layer being used for preventing metals in the first metal trace layer and the second metal trace layer from growing towards each other.

Abstract: The present disclosure relates to a display panel. The display panel may include a substrate. The substrate may include a display area, a dummy area inside the display area, and a boundary area between the dummy area and the display area on the substrate. The display substrate may further include an isolation protrusion on the substrate at the boundary area. The isolation protrusion may be configured to isolate a functional layer in the display area from the functional layer in the dummy area, and at least a side surface of the isolation protrusion facing the dummy area may be covered by an isolation inorganic layer.
