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, the circuit layer disposed on the base layer;
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;

a thin film encapsulation layer comprising an organic layer overlapping the plurality of insulation patterns and the organic light emitting diode, the thin film encapsulation layer disposed on the light emitting device layer; and
a touch sensing unit comprising at least one touch insulation layer, a plurality of touch electrodes, and a plurality of touch signal lines connected to the plurality of touch electrodes, the touch sensing unit disposed on the thin film encapsulation layer,
wherein:
at least a portion of the plurality of touch signal lines overlaps the plurality of insulation patterns;
the plurality of holes are arranged in an n×m matrix;
the plurality of insulation patterns comprise a first insulation pattern comprising a column portion and a row portion connected to the column portion; and
the row portion overlaps holes arranged in a column direction among the holes in the n×m matrix, and the row portion overlaps a hole disposed in a row direction of the holes arranged in the column direction.

2. The display device of claim 1 , wherein the plurality of insulation patterns further comprise:
a second insulation pattern;
a plurality of the first insulation patterns; and
the second insulation pattern disposed between two first insulation patterns spaced in the row direction.

3. 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;
an organic layer disposed on the light emitting device layer and overlapping the plurality of insulation patterns and the light emitting diode; and
a touch sensing unit comprising a plurality of touch electrodes and a plurality of touch signal lines connected to the plurality of touch electrodes, the touch sensing unit disposed on the organic layer,
wherein:
at least a portion of the plurality of touch signal lines overlaps the plurality of insulation patterns; and
the plurality of insulation patterns comprise first insulation patterns comprising a column portion extending along an edge of the base layer and a row portion connected to the column portion.

4. The display device of claim 3 , wherein the plurality of insulation patterns further comprise second insulation patterns disposed between two first insulation patterns spaced apart from each other.
