Thin film transistor and organic light emitting display device using the same |
摘要 |
There is provided a thin film transistor exhibiting stable reliability and electrical characteristics by forming an active layer by adding material having a large difference of electronegativity from oxygen like Hf and an atomic radius similar to that of Zn or SN to an oxide semiconductor made of ZnSnO to adjust concentration of carrier and to enhance reliability of the oxide semiconductor, and an organic light emitting display device having the same. |
