See full text

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.
