Organic light emitting diode display and method for manufacturing the same

An organic light emitting device comprising:

• a first pixel that displays a first color;
• a second pixel that displays a second color;
• and
• a third pixel that displays a third color,
• wherein the first pixel, second pixel and third pixel together form one pixel group,
• wherein each of the first pixel, the second pixel, and the third pixel comprises:
• a transflective pixel electrode that reflects light as well as transmits light,
• an organic emission layer on the pixel electrode and
• a reflective common electrode on the third color organic emission layer so that light may escape through the transflective pixel electrode to form a bottom emitting device,
• wherein:
• the first pixel further comprises a first transparent supplementary member disposed between the pixel electrode and the common electrode for adjusting an optical path length between the pixel electrode and the common electrode only in the first pixel,
• the organic emission layer of the first pixel comprises a first color organic emission layer and a third color organic emission layer disposed between the pixel electrode and the common electrode, and does not include a second color emission layer for emitting light of the second color,
• the organic emission layer of the second pixel comprises the second color organic emission layer and the third color organic emission layer disposed between the pixel electrode and the common electrode, and does not include the first color emission layer, and
• the third pixel does not include the first color organic emission layer and the second color organic emission layer.
