Abstract:
1. A display device, comprising a p-type thin film transistor and an n-type thin film transistor which are formed on a substrate, wherein: the p-type thin film transistor and the n-type thin film transistor each comprising: the drain electrode and the source electrode being formed so as to be opposed to each other with a clearance formed therebetween on a top surface of the semiconductor layer; the semiconductor layer of the p-type thin film transistor has, at each of an interface with the drain electrode and an interface with the source electrode, diffusion layers of p-type impurities formed therein; and the n-type thin film transistor further includes, at each of an interface between the drain electrode, which is formed in the same layer and is made of the same material as the drain electrode and the source electrode of the p-type thin film transistor, and the semiconductor layer and an interface between the source electrode, which is formed in the same layer and is made of the same material as the drain electrode and the source electrode of the p-type thin film transistor, and the semiconductor layer, semiconductor layers in which n-type impurities are doped.
