Abstract
Official abstract text for this publication.
An organic light-emitting display apparatus includes a thin film transistor including an active layer, a gate electrode, a source electrode, and a drain electrode, an organic light-emitting device including a pixel electrode connected to the thin film transistor, an intermediate layer including a light-emitting layer, and an opposed electrode, and a first wiring and a second wiring arranged in different layers on a substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic light-emitting display apparatus, comprising: a thin film transistor including an active layer, a gate electrode, a source electrode, and a drain electrode; an organic light-emitting device including a pixel electrode connected to the thin film transistor, an intermediate layer including a light-emitting layer, and an opposed electrode; a substrate that includes an active region in which the thin film transistor and the organic light-emitting device are formed, a sealant region outside the active region, and a pad portion region outside the sealant region, the sealant region being interposed between the pad portion region and the active region; and a first wiring and a second wiring arranged in different layers on the substrate, wherein at least one of the first wiring or the second wiring extends across the sealant region and is present in the active region and the pad region. 2. The apparatus as claimed in claim 1 , wherein the first wiring is formed on the same layer as the gate electrode, and the second wiring is formed on the same layer as the source and drain electrodes. 3. The apparatus as claimed in claim 1 , wherein: the second wiring extends across the sealant region and is present in the active region and the pad portion region. 4. The apparatus as claimed in claim 1 , wherein: the second wiring extends from the active region to at least a part of the sealant region. 5. The apparatus as claimed in claim 4 , further comprising at least one plug that electrically connects the first wiring and the second wiring that are overlapped with each other. 6. The apparatus as claimed in claim 5 , wherein: the at least one plug is located in at least one of the active region, the sealant region, and a boundary region between the active region and the sealant region. 7. The apparatus as claimed in claim 1 , further comprising an inorganic film that is formed on the opposed electrode. 8. The apparatus as claimed in claim 7 , wherein: the inorganic film is formed from the active region to the sealant region. 9. The apparatus as claimed in claim 8 , further comprising a sealant formed on the inorganic film in the sealant region. 10. The apparatus as claimed in claim 1 , wherein the first wiring extends across the sealant region and is present in the active region and the pad portion region. 11. An organic light-emitting display apparatus, comprising: a thin film transistor including an active layer, a gate electrode, a source electrode, and a drain electrode; an organic light-emitting device including a pixel electrode connected to the thin film transistor, an intermediate layer including a light-emitting layer, and an opposed electrode; a first wiring and a second wiring arranged in different layers on a substrate, and at least one plug that electrically connects the first wiring and the second wiring that are overlapped with each other.
