Abstract

A display device is disclosed that includes a display panel including a plurality of pixels configured to display an image. The display panel is divided into a plurality of areas including a first area and a second area. A pixel disposed adjacent to a boundary between the first area and a second area includes a separation layer.

First claim

What is claimed is:

1 . A display device comprising:
a display panel including a plurality of pixels which are configured to display an image, wherein the display panel is divided into a plurality of areas including a first area and a second area, and wherein a pixel disposed adjacent to a boundary between the first area and the second area includes a separation layer.

2 . The display device of claim 1 , wherein the separation layer extends parallel to the boundary, and is continuous.

3 . The display device of claim 2 , wherein the separation layer has a trapezoidal shape in a cross-sectional view.

4 . The display device of claim 2 , wherein the separation layer has an inverted trapezoidal shape in a cross-sectional view.

5 . The display device of claim 2 , wherein a first-first electrode included in a first pixel adjacent to the boundary in the first area and is electrically separated by the separation layer from a second-first electrode included in a second pixel adjacent to the boundary in the second area.

6 . The display device of claim 5 , wherein the first-first electrode and the second-first electrode are formed in a same layer, and
wherein voltages applied to the first-first electrode and the second-first electrode are different from each other.

7 . The display device of claim 5 , wherein the separation layer is formed on a pixel defining layer.

8 . The display device of claim 1 , wherein the separation layer includes one or more continuous sections parallel to the boundary and one or more discontinuous sections.

9 . The display device of claim 8 , wherein the continuous sections and the discontinuous sections are alternately disposed.

10 . The display device of claim 8 , wherein the separation layer has a trapezoidal shape in a cross-sectional view.

11 . The display device of claim 8 , wherein the separation layer has an inverted trapezoidal shape in a cross-sectional view.

12 . The display device of claim 8 , wherein, in the continuous section, a first-first electrode included in a first pixel adjacent to the boundary in the first area is electrically separated by the separation layer from a second-first electrode included in a second pixel adjacent to the boundary in the second area, and
wherein, in the discontinuous section, a third-first electrode included in a third pixel adjacent to the boundary in the first area is electrically connected to a fourth-first electrode included in a second pixel adjacent to the boundary in the second area.

13 . The display device of claim 12 , wherein the first-first electrode and the second-first electrode are formed in a same layer, and
wherein voltages applied to the first-first electrode and the second-first electrode are different from each other.

14 . The display device of claim 12 , wherein the separation layer is formed on a pixel defining layer.

15 . An electronic device comprising:
a display panel including a plurality of pixels which are configured to display an image; and an encapsulation layer disposed on the display panel, wherein the display panel is divided into a plurality of areas including a first area and a second area, and wherein a pixel disposed adjacent to a boundary between the first area and the second area includes a separation layer.

16 . The electronic device of claim 15 , further comprising:
a touch sensor disposed on the display panel; and a window disposed on the touch sensor.

17 . The electronic device of claim 15 , further comprising:
a data driver electrically connected to the display panel; a scan driver electrically connected to the display panel; and an emission driver electrically connected to the display panel.

18 . The electronic device of claim 15 , wherein the electronic device is a tablet PC, a television, a smartphone, a notebook computer, a head mounted display, a display included in an automobile dashboard, a navigation system display, a digital camera, an electronic book, or a portable game console.
