Abstract
An OLED display includes a substrate, a first electrode on the substrate, an organic emission layer on the first electrode, a second electrode on the organic emission layer, an insulating layer substantially covering the second electrode and having an opening that exposes a center portion of the second electrode, and a power supply electrically coupled with the second electrode through the opening of the insulating layer and configured to supply power to the second electrode.
Claims12
An organic light emitting diode (OLED) display device comprising:
- a substrate;
- a plurality of first electrodes on the substrate;
- a plurality of organic emission layers on respective ones of the first electrodes;
- a second electrode as a common electrode commonly on the plurality of organic emission layers for supplying power to all of the organic emission layers;
- an insulating layer substantially covering the second electrode and having a single opening for exposing a center portion of the second electrode;
- and
- a power supply electrically coupled with the second electrode through the opening of the insulating layer and configured to supply the power to all of the organic emission layers via the second electrode.
