Abstract
A bottom-surface emitting organic light emitting device and a method of manufacturing the organic light emitting device includes providing a transparent substrate, an organic light emitting diode (“OLED”) that includes a transparent electrode, an organic light emitting layer, and a pixel electrode sequentially stacked on an upper surface of the transparent substrate, a planarization film covering the OLED, and a pixel circuit that drives the OLED using an organic thin film transistor (“OTFT”) located on the planarization film.
