Abstract

A display device, including a substrate; a pixel electrode and an opposing electrode on the substrate; an encapsulation portion on the opposing electrode, the encapsulation portion including at least one organic layer and at least one inorganic layer alternately deposited; and a planarization layer on the encapsulation portion, the planarization layer including a portion covering an edge portion of the encapsulation portion, a first angle between an edge side surface of the planarization layer and a surface of the substrate being larger than a second angle between an edge side surface of the encapsulation portion and the surface of the substrate.

Claims (28)

1. A display device, comprising:

a substrate;

a transistor over the substrate;

a pixel electrode over the transistor and electrically connected to the transistor;

an opposing electrode over the pixel electrode;

an encapsulation portion over the opposing electrode, the encapsulation portion comprising a first inorganic layer and a first organic layer, the first organic layer being over the first inorganic layer;

a second organic layer comprising a portion over the encapsulation portion; and

a plurality of touch conductors comprising a conductor, the conductor being directly located on the encapsulation portion,

wherein:

the encapsulation portion is between the substrate and the second organic layer,

the second organic layer comprises a first portion and a second portion, and

a first distance between an upper surface of the first inorganic layer and a lower surface of the first portion is different from a second distance between the upper surface of the first inorganic layer and a lower surface of the second portion.

2. The display device as claimed in claim 1 , wherein the plurality of touch conductors comprises:

a plurality of touch electrodes in a touch sensible area of the substrate; and

a plurality of touch wires in a touch peripheral area of the substrate,

wherein the plurality of touch wires overlaps the second organic layer.

3. The display device as claimed in claim 2 , wherein the plurality of touch electrodes overlaps the second organic layer.

4. The display device as claimed in claim 2 , wherein the second organic layer overlaps an edge portion of the encapsulation portion.

5. The display device as claimed in claim 4 , wherein the edge portion of the encapsulation portion has an inclined surface approaching an edge of the substrate.

6. The display device as claimed in claim 5 , wherein at least a portion of the plurality of touch wires overlaps the inclined surface of the encapsulation portion in a plan view.

7. The display device as claimed in claim 6 , wherein the second organic layer is between the at least a portion of the plurality of touch wires and the inclined surface of the encapsulation portion in a sectional view.

8. The display device as claimed in claim 7 , wherein an upper surface of the second organic layer is substantially flat.

9. The display device as claimed in claim 2 , wherein:

the plurality of touch electrodes comprises first touch electrodes and a second touch electrode,

the plurality of touch wires comprises a first set of touch wires at a first side of the touch sensible area and a second set of touch wires at a second side, opposite the first side, of the touch sensible area,

the first touch electrodes are arranged in a plurality of rows,

the first set of touch wires is connected to odd-numbered rows of the plurality of rows, and

the second set of touch wires is connected to even-numbered rows of the plurality of rows.
