Abstract: The present disclosure discloses an organic light emitting display device. The organic light emitting display device includes a substrate, a driving transistor, a reflection electrode, a dielectric layer, a first and second electrode, and an organic light emitting layer. The driving transistor is in each of a plurality of pixel regions which are defined on the substrate. The reflection electrode is on the driving transistor, and is electrically connected to a gate electrode of the driving transistor. The dielectric layer is on the reflection electrode. The first electrode is on the dielectric layer, and is electrically connected to a source electrode of the driving transistor, and faces the reflection electrode. The organic light emitting layer is on the first electrode. The second electrode is on the organic light emitting layer.
