ORGANIC LIGHT EMITTING DISPLAY APPARATUS AND METHOD OF MANUFACTURING THE SAME

摘要

The present invention relates to an organic light emitting display device having a plurality of pixels on a substrate. Each of the pixels comprises: an organic light emitting element including a first electrode, a second electrode, and an intermediate layer disposed between the first electrode and the second electrode and having an organic light emitting layer; a driving TR which drives the organic light emitting element and includes an active layer, a gate electrode, a source electrode, and a drain electrode; and a switching TR which is electrically connected to the driving TR and includes an active layer, a gate electrode, a source electrode, and a drain electrode. The gate electrode of the driving TR is disposed between a first conductive layer and the active layer of the driving TR and has a second conductive layer formed smaller than the first conductive layer. The gate electrode of the switching TR is formed of the same material as the first conductive layer.
