Abstract: Provided is an organic light emitting display device in which a plurality of pixel areas each including an emitting area and a non-emitting area is defined in a display area. The organic light emitting display device includes: an auxiliary electrode in a part of a non-emitting area of at least one pixel area; an auxiliary electrode contact portion formed as a part of the auxiliary electrode; a first electrode in the emitting areas of the plurality of pixel areas; an organic layer on the first electrode and the auxiliary electrode; and a second electrode on the organic layer. The auxiliary electrode contact portion electrically connects the auxiliary electrode and the second electrode. A distance from a center of the auxiliary electrode contact portion to a terminal end of the first electrode in the emitting area may be 3 μm or more.

Abstract: A thin film transistor substrate having two different types of thin film transistors on the same substrate, and a display using the same are discussed. The thin film transistor substrate can include a substrate, a first thin film transistor (TFT), a second TFT, a first storage capacitor electrode, an oxide layer, a nitride layer, a second storage capacitor electrode, a planar layer and a pixel electrode. The first TFT is disposed in a first area, the second TFT is disposed in a second area, and the first storage capacitor electrode is disposed in a third area on the substrate respectively. The oxide layer covers the first and second TFTs, and exposes the first storage capacitor electrode. The nitride layer is disposed on the oxide layer and covers the first storage capacitor electrode. The second storage capacitor electrode overlaps with the first storage capacitor electrode on the nitride layer. The planar layer covers the first and second TFTs, and the second storage capacitor electrode. The pixel electrode is disposed on the planar layer.
