Abstract

The present disclosure relates to a narrow bezel large area organic light emitting diode display. An organic light emitting diode display includes a substrate having a display area and a non-display area; a gate driver disposed in the non-display area; a ground line overlapping on the gate driver with a passivation layer; an anode electrode disposed in the display area; an organic light emission layer disposed in the display area and stacked on the anode electrode; and a cathode electrode stacked on the organic light emission layer and contacting the ground line.

Claims (20)

1. An organic light emitting diode display, comprising:

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

a gate driver disposed in the non-display area;

a ground line overlapping on the gate driver with a passivation layer;

an anode electrode disposed in the display area;

an organic light emission layer disposed in the display area and stacked on the anode electrode; and

a cathode electrode stacked on the organic light emission layer and contacting the ground line.

2. The organic light emitting diode display according to the claim 1 , further comprising:

a thin film transistor disposed in the display area and contacting the anode electrode; and

an auxiliary cathode electrode including the same material with the anode electrode, separated from the anode electrode, and contacting the ground line.

3. The organic light emitting diode display according to the claim 2 , further comprising:

a planar layer disposed on the ground line and the thin film transistor, and exposing some portions of the ground line and the thin film transistor,

wherein the anode electrode and the auxiliary cathode electrode are disposed on the planar layer,

wherein the auxiliary cathode electrode contacts the ground line exposed from the planar layer, and

wherein the cathode electrode contacts the auxiliary cathode electrode and the ground line.

4. The organic light emitting diode display according to the claim 1 , further comprising:

a thin film transistor disposed in the display area and contacting the anode electrode;

a first storage electrode overlapping with the thin film transistor on a first passivation layer; and

a second storage electrode overlapping with the first storage electrode with a second passivation layer,

wherein the ground line is disposed on a same layer and includes a same material with any one of the first storage electrode and the second storage electrode.
