Patent ID: 8288784

Claim:
An organic light emitting display device comprising: a substrate; and a plurality of pixels on the substrate, each being configured to emit light of one of a plurality of second colors for forming white light when combined, the plurality of pixels comprising: a plurality of first electrodes; a second electrode; a white light emitting layer between the first electrodes and the second electrode and comprising a plurality of light emitting layers, each being configured to emit light of one of a plurality of first colors for forming white light when combined; a first thin film layer between the first electrodes and the second electrode, the first thin film layer having a plurality of thicknesses corresponding to the plurality of second colors; and color filters in only some of the plurality of pixels based on the color of light emitted by the some of the plurality of pixels, wherein each of the plurality of pixels is further configured to emit light of the one of the plurality of second colors when white light emitted from the white light emitting layer causes resonance to occur between the first electrodes and the second electrode.
