Claim 11:
12. The method for fabricating a displaying base plate according to claim 11, wherein after the step of patterning the one side of the first flat layer that is further away from the substrate to form the first metal trace and the bonding block, the method further comprises:
forming the second flat layer on sides of the first metal trace, the first flat layer and the bonding block that are further away from the substrate;
forming a passivation layer on the sides of the second flat layer and the bonding block that are further away from the substrate, wherein an orthographic projection of the passivation layer on the substrate covers the orthographic projection of the second flat layer on the substrate; and
forming the second metal layer on one side of the passivation layer and one exposed side of the bonding block that are further away from the substrate.
