Claim Text:
1. An organic light-emitting display device comprising: a substrate; a plurality of pixels on the substrate, each of the pixels comprising a first sub-pixel, a second sub-pixel, and a third sub-pixel for emitting different colors of light, respectively; an insulating layer on the substrate; a first organic light-emitting device on the insulating layer at the first sub-pixel, and sequentially comprising a first pixel electrode, a first organic emission layer (EML) for emitting white light, and an opposite electrode; a first color filter between the insulating layer and the first pixel electrode, and configured to transmit blue light; a second organic light-emitting device on the insulating layer at the second sub-pixel, and sequentially comprising a second pixel electrode, the first organic EML for emitting white light, and the opposite electrode; a second color filter between the insulating layer and the second pixel electrode, and configured to transmit green light; a third organic light-emitting device on the insulating layer at the third sub-pixel, and sequentially comprising a third pixel electrode, a second organic EML for emitting a purple light comprising a red color and a blue color, and the opposite electrode; and a third color filter between the insulating layer and the third pixel electrode, and comprising a first region for transmitting red light and a second region for transmitting the purple light, wherein the transmitted purple light combines with the transmitted red light and the combined light has a dominant wavelength different from that of the transmitted red light alone.
