Abstract:
1. A method for manufacturing a display device comprising the steps of: forming a gate electrode comprising a chained metal body of particles over a substrate having an insulating surface; forming a gate insulating layer over the gate electrode, forming a semiconductor layer over the gate electrode with the gate insulating layer therebetween, forming an insulating layer over the semiconductor layer; forming a first mask in a position overlapping with the gate electrode with a droplet discharge method; forming a channel protective layer by etching the insulating layer by using the first mask; forming a semiconductor layer containing one conductivity type impurity; forming a second mask over the gate electrode with a droplet discharge method; etching the semiconductor layer containing one conductivity type impurity and the semiconductor layer by using the second mask; forming source and drain wirings over the semiconductor layer containing one conductivity type impurity with a droplet discharge method; and etching the semiconductor layer containing one conductivity type impurity over the channel protective layer by using the source and drain wirings as masks.
