Abstract

An organic light-emitting display device may comprise: a substrate; a first active layer provided on the substrate; a gate insulating layer; a first gate electrode; a first interlayer insulating layer and a second interlayer insulating layer; a first source electrode which is provided on the second interlayer insulating layer and contacts the first active layer via a contact hole formed by removing portions of the gate insulating layer, the first interlayer insulating layer, and the second interlayer insulating layer; a protective insulating layer provided on the first source electrode; a first drain electrode which is provided on the protective insulating layer and contacts the first active layer via a contact hole formed by removing portions of the gate insulating layer, the first interlayer insulating layer, the second interlayer insulating layer, and the protective insulating layer; and a sub-pixel structure provided on the first drain electrode.

Description

technical field [0001] Embodiments generally relate to organic light emitting display devices. More particularly, embodiments of the inventive concept relate to organic light emitting display devices including transistors of different types from each other. Background technique [0002] A flat panel display device is used as a display device replacing a cathode ray tube display device due to its light-weight and thin characteristics. As typical 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 light emitting display device with high resolution, the organic light emitting display device may include a relatively large number of signal wirings. When the organic light emitting display device includes ...
