Display device with integrated touch screen
Disclosed is a display device with integrated touch screen, which can prevent a first touch electrode or a second touch electrode from being short-circuited with a bridge electrode through an opening. The display device includes first electrodes on a first substrate, a light emitting layer on the first electrodes, a second electrode on the light emitting layer, an encapsulation layer on the second electrode, a bridge electrode and a dummy electrode on the encapsulation layer, an insulation layer covering the bridge electrode and the dummy electrode, and a first touch electrode and a second touch electrode on the insulation layer. The first touch electrode is electrically connected to the bridge electrode, and bridge electrode is spaced apart from the dummy electrode.
1. A display device comprising:
a substrate;
a thin film transistor layer on the substrate;
a light emitting device layer on the thin film transistor layer, the light emitting device layer including a light emitting region and a non-light emitting region;
an encapsulation layer on the light emitting device layer;
a bridge electrode and a dummy electrode at a same layer on the encapsulation layer, the bridge electrode being spaced apart from the dummy electrode, the dummy electrode being disposed at an overlapping location with the non-light emitting region;
an insulation layer on the bridge electrode and the dummy electrode; and
a first touch electrode and a second touch electrode on the insulation layer, the first touch electrode electrically connected to the bridge electrode through a first contact hole of the insulation layer.
2. The display device of claim 1 , wherein the first touch electrode and the second touch electrode are disposed on the same layer.
3. The display device of claim 1 , wherein the bridge electrode and the dummy electrode are disposed between the encapsulation layer and the insulation layer.
4. The display device of claim 3 , wherein the dummy electrode is overlapped with the first touch electrode and the second touch electrode.
5. The display device of claim 4 , wherein the first touch electrode is connected to the dummy electrode through a second contact hole which passes through the insulation layer and exposes the dummy electrode.
6. The display device of claim 5 , wherein the second touch electrode is connected to the dummy electrode through a third contact hole which passes through the insulation layer and exposes the dummy electrode.
7. The display device of claim 3 , wherein the bridge electrode is electrically insulated from the dummy electrode.
8. The display device of claim 7 , wherein the dummy electrode is a floating electrode.
