Patent ID: 8330354

Claim:
An organic electro-luminescent display device comprising: a first electrode disposed on a first substrate; a buffer pattern disposed on the first electrode that defines a light emission region associated with a pixel; a pair of separators disposed on the buffer pattern positioned on opposite sides of the pixel; a protrusion member disposed on the buffer pattern within the light emission region defined by the pair of separators; an organic light emission layer disposed on the first electrode within the light emission region; a second electrode with a portion disposed on the organic light emission layer and a contact portion disposed on the protrusion member; a first gather electrode configured to directly contact an entire surface of the second electrode and formed of an oxidation-resistant electrically conductive material; a second gather electrode configured to directly contact an entire surface of the first gather electrode and formed of an electrically conductive gather material; and a second substrate, opposite to the first substrate that includes a driver element configured to directly contact the second gather electrode, wherein the first and second gather electrodes are disposed on at least opposite sides of the contact portion, wherein the electrically conductive gather material includes at least one of Ca, Sr, and CaO, wherein the oxidation-resistant electrically conductive material has an oxidative capacity lower than that of the electrical conductive gather material.
