1. An organic light emitting device, comprising:
- a first electrode;
a second electrode; and
an organic emissive layer disposed between the first electrode and the second electrode;
wherein, for each of a plurality of points on the first electrode, the potential difference between the point on the first electrode and a corresponding point on the second electrode, is within 5% of the potential difference between each of the other plurality of points on the first electrode and a corresponding point on the second electrode;
wherein, for each point on the first electrode, the point and the corresponding point on the second electrode lie on a line that is substantially perpendicular to the first electrode and to the second electrode.

Abstract
Provided are an OLED device and a method of manufacturing the OLED device that may provide improved luminance uniformity. The disclosed OLED may have a first electrode that has a first sheet resistance Rs, and a second electrode that has a second sheet resistance, wherein the second sheet resistance may be in the range of 0.3 Rs-1.3 Rs. In addition, the disclosed OLED may have a plurality of equal potential difference between points on a first electrode and a second electrode. The equal potential difference may be provided by a gradient resistance formed on at least one of the electrodes.
