Abstract
An organic light emitting display apparatus using a micro cavity method comprises a first sub pixel, a second pixel and a third pixel, each of which emits different color from an emission layer interposed between two electrodes. The first sub pixel, the second sub pixel and the third sub pixel form a unit pixel. Emission layers of the first and second sub pixels are formed so as to have the same pattern throughout the first and second sub pixels, and an emission layer of the third sub pixel is formed so as to have a pattern separate from the first and second sub pixels. In this structure, three-colored emission layers may be formed using two mask processes so that productivity is improved due to process simplification, and high-resolution is realized due to a decrease in the distance between deposited patterns.
