An organic light-emitting display device may comprise: a substrate having a light-emitting area including a first area and a second area; a first active layer disposed in the first area on the substrate and having source and drain areas; a first gate electrode disposed on the first active layer; a first source electrode disposed on the first gate electrode and connected to the source area; a sacrificial layer structure disposed to be spaced apart from the first source electrode and having an opening; a protective insulating layer disposed on the first source electrode and the sacrificial layer structure; a first drain electrode disposed on the protective insulating layer, connected to the drain area through the opening, and defined as a first transistor alongside the first active layer, the first gate electrode, and the first source electrode; and a sub-pixel structure disposed on the first transistor.
Description
technical field [0001] Embodiments generally relate to organic light emitting display devices and methods of manufacturing organic light emitting display devices. More particularly, embodiments of the inventive concept relate to an organic light emitting display device including transistors of different types from each other and a method of manufacturing the organic light emitting display device including transistors of different types from each other. Background technique [0002] Flat panel display devices are used as display devices for replacing cathode ray tube display devices due to their lightweight and thin characteristics. As representative examples of such flat panel display devices, there are liquid crystal display devices and organic light emitting display devices. [0003] Recently, organic light emitting display devices including silicon-based semiconductor elements and metal oxide-based semiconductor elements have been developed. In order to drive an organic...
