A semiconductor device includes a conductive layer with a plurality of wires, and a bonding pad formed in a region overlapping with the plurality of wires of the conductive layer. One of the wires is connected to the bonding pad, and an insulating protective film is formed between the remaining wires and the bonding pad. The protective film is bridged between adjacent wires at least in a region overlapping with the bonding pad. As a result, the protective film on the wires forms a bridge structure, which is effective in preventing cracking at a lower portion of the protective film. Further, a void formed underneath the bridged portion serves as an air spring to prevent damage to the structural elements, such as the wires, formed under the protective film. Further, because a polyimide film, which serves as a shock absorber, is not required, working efficiency can be improved and chip cost can be reduced.
