Abstract

An organic light emitting diode display includes a substrate including a display area and a non-display area, subpixels arranged in the display area in a matrix form, a contact electrode that is formed in the non-display area, transfers a power received from the outside, and includes at least one of electrodes included in each subpixel, and a contact unit that includes at least one of insulating layers included in each subpixel and exposes a portion of the contact electrode. An upper electrode included in each subpixel is formed in the display area and the non-display area and is electrically connected to the contact electrode through the contact unit.

Claims (39)

1. An organic light emitting diode display comprising:

a substrate including a display area and a non-display area;

subpixels arranged in the display area in a matrix form;

a contact electrode that is formed in the non-display area, transfers a power received from the outside, and includes at least one of electrodes included in each subpixel; and

a contact unit including at least one of insulating layers included in each subpixel, the contact unit exposing a portion of the contact electrode,

wherein an upper electrode included in each subpixel is formed in the display area and the non-display area and is electrically connected to the contact electrode through the contact unit,

wherein the contact electrode is formed as a gate electrode included in each subpixel,

wherein the insulating layer formed in the contact unit includes at least three of the insulating layers included in each subpixel.

2. The organic light emitting diode display of claim 1 , wherein the contact electrode is formed using the same process and the same material as at least one of the electrodes included in each subpixel,

wherein the insulating layer formed in the contact unit is formed using the same process and the same material as at least one of the insulating layers included in each subpixel.

3. The organic light emitting diode display of claim 1 , wherein at least two insulating layers are formed under the contact electrode, and the contact electrode is formed as a source electrode and a drain electrode included in each subpixel,

wherein the insulating layer formed in the contact unit includes at least one of the insulating layers included in each subpixel.

4. The organic light emitting diode display of claim 1 , wherein the contact electrode is formed as a gate electrode, a source electrode, and a drain electrode included in each subpixel,

wherein the insulating layer formed in the contact unit includes at least one of the insulating layers included in each subpixel.

5. The organic light emitting diode display of claim 1 , wherein the contact electrode is formed as a gate electrode, a source electrode, a drain electrode, and a lower electrode included in each subpixel.

6. An organic light emitting diode display comprising:

a substrate including a display area and a non-display area;

subpixels arranged in the display area in a matrix form;

a contact electrode that is formed in the non-display area, transfers a power received from the outside, and includes at least one of electrodes included in each subpixel; and

a contact unit including at least one of insulating layers included in each subpixel, the contact unit exposing a portion of the contact electrode,

wherein an upper electrode included in each subpixel is formed in the display area and the non-display area and is electrically connected to the contact electrode through the contact unit,

wherein at least three insulating layers are formed under the contact electrode, and the contact electrode is formed as a lower electrode included in each subpixel,

wherein the insulating layer formed in the contact unit includes at least one of the insulating layers included in each subpixel.

7. An organic light emitting diode display comprising:

a substrate including a display area and a non-display area;

wherein an upper electrode included in each subpixel is formed in the display area and the non-display area and is electrically connected to the contact electrode through the contact unit,

wherein the contact electrode is formed as a gate electrode and a lower electrode included in each subpixel,

wherein the insulating layer formed in the contact unit includes at least three of the insulating layers included in each subpixel.

8. An organic light emitting diode display comprising:

a substrate including a display area and a non-display area;

subpixels arranged in the display area in a matrix form;

a contact electrode that is formed in the non-display area, transfers a power received from the outside, and includes at least one of electrodes included in each subpixel; and

a contact unit including at least one of insulating layers included in each subpixel, the contact unit exposing a portion of the contact electrode,

wherein an upper electrode included in each subpixel is formed in the display area and the non-display area and is electrically connected to the contact electrode through the contact unit,
