Abstract
An organic EL display device driven by thin-film transistors is disclosed, wherein for suppressing the deterioration with time of thin-film transistors, at least one of the thin-film transistors, or a second thin-film transistor is formed of a p-channel type thin-film transistor. The p-channel type thin-film transistor has been formed in the same step of process as the thin-film transistors in built-in drive circuits.
