Abstract

An organic light emitting display device is provided. The organic light emitting display device includes a substrate, a first semiconductor element, a second semiconductor element, a protection electrode, and a light emitting structure. The protection electrode is disposed between the second active layer and the second source electrode and the second drain electrode, and has an opening that exposes a portion of the second active layer and the light emitting structure is disposed on the first and second semiconductor elements.

Description

technical field [0001] Example embodiments generally relate to an organic light emitting display device and a method of manufacturing the organic light emitting display device. More particularly, embodiments of the inventive concepts relate to organic light emitting display devices including silicon-based semiconductor elements and metal oxide-based semiconductor elements and methods of manufacturing organic light-emitting display devices including silicon-based semiconductor elements and metal oxide-based semiconductor elements. Background technique [0002] Since flat panel display ("FPD") devices are lightweight and thin compared to cathode ray tube ("CRT") display devices, FPD devices are widely used as display devices for electronic devices. Typical examples of FPD devices are liquid crystal display ("LCD") devices and organic light emitting display ("OLED") devices. [0003] Recently, OLED devices including silicon-based semiconductor elements and metal oxide-based se...
