Organic light emitting diode display

An organic light emitting diode display, comprising:

• a substrate including a plurality of sub-pixels, each sub-pixel comprising a display area and a non-display area surrounding the display area, the display area comprising a first display area at a center region of the display area and a second display area surrounding the first display area;
• a first electrode formed in the display area;
• an organic light emitting layer formed on the first electrode and extending to the non-display area;
• a third electrode formed on a portion of the organic light emitting layer in the first display area;
• and
• a second electrode formed on the third electrode and the organic light emitting layer,
• wherein the first and third electrodes are able to achieve a micro cavity effect,
• wherein the third electrode of at least one of the sub-pixels is separated from the third electrode of another of the sub-pixels neighboring the at least one of the sub-pixels,
• wherein a width of the first electrode is larger than a width of the third electrode, and
• wherein side surfaces at opposite edges of the third electrode contact the organic light emitting layer.
