Organic light emitting display panel and organic light emitting display apparatus using the same

Abstract:

An organic light emitting display panel can include a substrate; pixels disposed on the substrate; a driving transistor including: a driving active layer, a driving gate electrode overlapping with the driving active layer, a driving first conductor extended from one end of the driving active layer, a driving second conductor extended from the other end of the driving active layer, and a driving first gate insulating film overlapping with the driving active layer; a switching transistor including: a switching active layer, a switching gate electrode overlapping with the switching active layer, a switching first conductor extended from one end of the switching active layer, a switching second conductor extended from the other end of the switching active layer, and a switching first gate insulating film overlapping with the switching active layer; an organic light emitting diode; and a second gate insulating film disposed between the driving and switching gate electrodes of the driving and switching transistors, and the driving first conductor, the driving second conductor, the driving first gate insulating film, the switching first conductor, the switching second conductor and the switching first gate insulating film.
