Classification: CPC H | IPC H

Claim 10:
11. A method for fabricating a displaying base plate, wherein the fabricating method comprises:
providing a substrate;
forming a first flat layer on one side of the substrate;
patterning one side of the first flat layer that is further away from the substrate to form a first metal layer;
forming a second flat layer on sides of the first metal layer and the first flat layer that are further away from the substrate; and
forming a second metal layer on one side of the second flat layer that is further away from the substrate;
wherein the first metal layer comprises a first metal trace, an orthographic projection of the second metal layer on the substrate and an orthographic projection of the first metal trace on the substrate have an overlapping part, and an orthographic projection of the second flat layer on the substrate covers the orthographic projection of the first metal trace on the substrate;
wherein the displaying base plate further comprises a passivation layer, the passivation layer is located between the second flat layer and the second metal layer, and an orthographic projection of the passivation layer on the substrate covers the orthographic projection of the second flat layer on the substrate;
wherein the first metal layer further comprises a bonding block, and the bonding block and the first metal trace are insulated and separate; and
the bonding block is located between the substrate and the second metal layer;
wherein the binding region of the second metal layer contacts the bonding block.
