Abstract

An organic light emitting diode display device, including a flexible substrate; pixels on the flexible substrate, the pixels including an organic emission layer; a pixel definition layer between the pixels, the pixel definition layer including openings; an encapsulation layer covering the pixels; and a conductive light shielding member on the encapsulation layer, the conductive light shielding member not overlapped with the pixels, and overlapped with the pixel definition layer.

Claims (13)

1. An organic light emitting diode display device, comprising:

a flexible substrate;

pixels on the flexible substrate, the pixels including an organic emission layer;

a pixel definition layer between the pixels, the pixel definition layer including openings;

an encapsulation layer covering the pixels; and

a conductive light shielding member on the encapsulation layer, the conductive light shielding member:

not being overlapped with the pixels, and

being overlapped with the pixel definition layer,

wherein the conductive light shielding member is electrically connected to a ground electrode of a pad part outside the encapsulation layer.

2. The organic light emitting diode display device as claimed in claim 1 , wherein the pixels are in a matrix form.

3. The organic light emitting diode display device as claimed in claim 1 , wherein the conductive light shielding member includes a carbon black and a polymer organic material.

4. The organic light emitting diode display device as claimed in claim 3 , wherein a content of carbon black in the conductive light shielding member is 30 weight % or less.

5. The organic light emitting diode display device as claimed in claim 1 , wherein the conductive light shielding member is formed by an inkjet printing method.
