Abstract

A display device including a base layer, a circuit layer, a light emitting device layer, an organic layer, and a touch sensing unit. The base layer includes a display area and a non-display area. A plurality of insulation patterns overlaps the non-display area. The organic layer is disposed on the light emitting device and overlaps the plurality of insulation patterns and the organic light emitting diode. At least a portion of the plurality of touch signal lines overlaps the plurality of insulation patterns.

First claim

What is claimed is:

1. A display device comprising:
a base layer comprising a display area and a non-display area;
a circuit layer comprising at least one intermediate insulation layer and a power supply electrode overlapping the non-display area;
a light emitting device layer comprising:
an organic light emitting diode comprising a first electrode disposed on the circuit layer, a light emitting layer, and a second electrode;
a pixel definition layer comprising an opening for exposing the first electrode;
a connection electrode connecting the second electrode and the power supply electrode, the connection electrode comprising a plurality of holes; and
a plurality of insulation patterns overlapping the holes and including control insulation patterns spaced apart from each other; and

a thin film encapsulation layer comprising an organic layer overlapping the control insulation patterns and the organic light emitting diode, the thin film encapsulation layer disposed on the light emitting device layer;
wherein:
the organic layer does not have a hole overlapping the display area;
the plurality of holes define a plurality of rows and the plurality of rows are arranged in a first direction;
a first row among the plurality of rows comprises first holes arranged in a second direction intersecting the first direction;
a second row among the plurality of rows comprises second holes arranged in the second direction and at least a part of the second holes disposed between the first holes; and
a third row among the plurality of rows is arranged in the second direction and comprises second holes corresponding to the first holes.

2. The display device of claim 1 , wherein each of the plurality of holes is covered by a corresponding insulation pattern among the plurality of insulation patterns.

3. The display device of claim 1 , wherein the connection electrode comprises a first transparent conductive layer, a metal layer disposed on the first transparent conductive layer, and a second transparent conductive layer disposed on the metal layer.

4. The display device of claim 1 , wherein the control insulation patterns have the same thickness and the same material as the pixel definition layer.

5. The display device of claim 1 , wherein the non-display area comprises:
a first non-display area and a second non-display area facing each other in the first direction with the display area arranged therebetween; and
a third non-display area and a fourth non-display area facing each other in the second direction intersecting the first direction with the display area arranged therebetween,
wherein:
the power supply electrode is disposed at least in the first non-display area, the third non-display area, and the fourth non-display area; and
the connection electrode is disposed at least in the third non-display area and the fourth non-display area.

6. The display device of claim 5 , further comprising a dam disposed at least in the first non-display area, the third non-display area, and the fourth non-display area, and
wherein the dam overlaps the power supply electrode.

7. The display device of claim 6 , wherein the dam has the same thickness and the same material as the pixel definition layer or the at least one intermediate insulation layer.

8. The display device of claim 1 , wherein the second electrode overlaps a least a portion of the plurality of insulation patterns.

9. The display device of claim 1 , wherein the connection electrode comprises the same layer structure and the same material as the first electrode.

10. A display device comprising:
a base layer comprising a display area and a non-display area;
a circuit layer disposed on the base layer;
a light emitting device layer comprising a light emitting diode disposed on the circuit layer, a pixel definition layer comprising an opening for exposing a first electrode of the light emitting diode, and a plurality of insulation patterns overlapping the non-display area and including control insulation patterns spaced apart from each other; and
an organic layer disposed on the light emitting device layer and overlapping the control insulation patterns and the light emitting diode;
wherein:
the organic layer does not have a hole overlapping the display area;
the control insulation patterns define a plurality of rows and the plurality of rows are arranged in a first direction;
a first row among the plurality of rows comprises first insulation patterns arranged in a second direction intersecting the first direction;
a second row among the plurality of rows comprises second insulation patterns arranged in the second direction and at least a part of the second insulation patterns disposed between the first insulation patterns; and

a third row among the plurality of rows comprises third insulation patterns arranged in the second direction and corresponding to the first insulation patterns.
