摘要： A light emitting display device that includes thin film transistors. Material for electrodes of the thin film transistors are chosen to allow for dehydrogenation of the underlying semiconductor pattern while allowing for high frequency driving without delay. Molybdenum is chosen to allow for dehydrogenation, and titanium on aluminum two-layered structure is chosen for low resistance and high-speed driving. The display includes a driving transistor and a switching transistor with a polycrystalline semiconductor layer and a transistor with an oxide semiconductor layer.
