Abstract:
1. organic light emitting display apparatus comprising a plurality of unit pixels, each unit pixel having at least two sub pixels, a first one of the sub pixels to emit only a first color of light and a second one of the sub pixels to emit only a second color of light, the first and second colors of light being different colors of light, and each of the at least two sub pixels including: a first resonance region; a second resonance region; first and second electrodes, the second electrode extending over the first electrode; and an intermediate layer disposed between the first and second electrodes, the intermediate layer including an emission layer, wherein in each of the at least two sub pixels: a first portion of the first electrode, a first portion of the second electrode, and a first portion of the intermediate layer extends within the first resonance region, the first resonance region to induce a first resonance of light based on light generated by the first portion of the intermediate layer including the emission layer between the first and second electrodes, and a second portion of the first electrode, a second portion of the second electrode, and a second portion of the intermediate layer extends within the second resonance region, the second resonance region to induce a second resonance of light based on light generated by the second portion of the intermediate layer including the emission layer between the first and second electrodes, the second resonance being stronger than the first resonance.
