1. 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; and
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,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.

Abstract
An organic light emitting display device includes a substrate and a plurality of pixels on the substrate. The pixels include a plurality of first electrodes, a second electrode, a white light emitting layer, and a first thin film layer between the first electrodes and the second electrode. White light emitted from the white light emitting layer causes resonance to occur between the first electrodes and the second electrode.

20. An organic light emitting display device comprising:
-
a substrate; and a plurality of pixels on the substrate, each being configured to emit red, green, or blue light, 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 light emitting layers configured to emit red, green, and blue light 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 first thickness in each of the plurality of pixels configured to emit red light, a second thickness different than the first thickness in each of the plurality of pixels configured to emit green light, and a third thickness different than the first and second thicknesses in each of the plurality of pixels configured to emit blue light; 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 the one of red light, green light, or blue light when white light emitted from the white light emitting layer causes resonance to occur between the first electrodes and the second electrode, and wherein light in the only some of the plurality of pixels is emitted through the color filters in the only some of the plurality of pixels, and wherein light in remaining ones of the plurality of pixels is emitted without passing through the color filters. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)
