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

Abstract:

An organic light emitting display panel and an organic light emitting display apparatus using the same are disclosed, in which a switching transistor and a driving transistor are provided on their respective layers different from each other. To this end, the organic light emitting display panel comprises a substrate partitioned by a plurality of pixels, a driving transistor provided in a first pixel of the pixels and provided on the substrate in a top gate type, a first insulating film for covering the driving transistor, a switching transistor provided on the first insulating film in a top gate type, a second insulating film for covering the first insulating film and the switching transistor, a planarization film provided on the second insulating film, and an organic light emitting diode provided on the planarization film and connected with a driving first conductor of the driving transistor.
