Abstract

Provided is an organic light-emitting display device that includes: a substrate; a first wiring that extends in a first direction on the substrate and comprises first and second portions with an opening therebetween; a second wiring that overlaps with the opening and extends in a second direction that crosses the first direction; an insulating film that covers the first wiring and the second wiring and comprises a first contact hole that exposes the first portion of the first wiring and a second contact hole that exposes the second portion; and a bridge electrode that is formed on the insulating film, is electrically connected to the first and second portions through the first and second contact holes, and comprises a transparent conductive oxide and a metal.

Claims (31)

1. An organic light-emitting display device comprising:

a substrate;

a first wiring that extends in a first direction on the substrate, and comprises first and second portions with an opening therebetween, the opening being entirely filled by a first insulating film;

a second wiring that overlaps with the opening and extends in a second direction that crosses the first direction;

a second insulating film that covers the first wiring and the second wiring, the second insulating film comprising

a first contact hole that exposes the first portion of the first wiring and

a second contact hole that exposes the second portion; and

a bridge electrode that is formed on the second insulating film, is electrically connected to the first and second portions through the first and second contact holes, respectively, and comprises a transparent conductive oxide and a metal, and wherein a distance between the substrate and the first wiring is shorter than a distance between the substrate and the second wiring.

2. The organic light-emitting display device of claim 1 , further comprising a thin film transistor (TFT) that comprises

a gate electrode formed on the substrate,

an active layer insulated from the gate electrode,

a source electrode and a drain electrode formed on the active layer,

the first wiring formed at a same level as the gate electrode,

the second wiring formed at a same level as the source electrode and the drain electrode.

3. The organic light-emitting display device of claim 2 , the active layer comprising a semiconductive oxide.

4. The organic light-emitting display device of claim 2 , further comprising

a pixel electrode formed on the second insulating film and connected to the TFT,

an intermediate layer formed on the pixel electrode, and

a facing electrode formed on the intermediate layer.

5. The organic light-emitting display device of claim 4 , further comprising a bus line comprised of same material of the bridge electrode, formed at a same level as the bridge electrode, and connected to the facing electrode.

6. The organic light-emitting display device of claim 4 , the organic light-emitting device emitting light from the intermediate layer towards the facing electrode.

7. The organic light-emitting display device of claim 1 , further comprising a TFT that comprises

a gate electrode formed on the substrate,

an active layer insulated from the gate electrode,

a source electrode and a drain electrode formed on the active layer,

the first wiring formed at a same level as the source electrode and the drain electrode, and

the second wiring formed at a same level as the gate electrode.

8. The organic light-emitting display device of claim 1 , the bridge electrode comprising:

a first layer comprising indium tin oxide (ITO),

a second layer comprising silver (Ag), and

a third layer comprising ITO.
