Abstract
A drive backboard includes: a first conductive layer including bonding pins and first connecting lines, an insulating layer including first via holes and second via holes, a second conductive layer including connecting electrodes and second connecting lines and a conductive protective layer including first protective structures and second protective structures. The first via hole exposes the bonding pin, one end of a first connecting line electrically connects a bonding pin, and the other end reaches the second via hole. One end of a second connecting line electrically connects a connecting electrode, and the other end electrically connects the first connecting line through the second via hole. The first protective structure covers the bonding pin, and the second protective structure covers the second connecting line formed at the position of the second via hole. The pattern of the conductive protective layer is complementary to the pattern of the insulating layer.
