Organic light emitting device and manufacturing method of the same

摘要

The present invention relates to an organic light emitting device including a substrate (110), first (121) and second signal lines (171) formed on the substrate (110), a switching transistor connected to the first (121) and second (171) signal lines and including a first semiconductor (154a), a driving transistor connected to the switching transistor and including a second semiconductor (154b), a first electrode (191) connected to the driving transistor, a second electrode (270) facing the first electrode (191), and a light emitting member (370) formed between the first electrode (191) and the second electrode (270). The first semiconductor (154a) and the second semiconductor (154b) are formed on different layers of the display.
