A color organic light-emitting display device having an array of pixels divided into at least two different color pixel sets each color pixel set emitting a different predetermined color light over a common substrate, wherein each pixel in the array includes a metallic bottom-electrode layer (12T) disposed over the substrate (10) and a metallic electrode layer (16R) spaced from the metallic bottom-electrode layer; wherein the material for reflective metallic electrode layer (16R) includes Ag, Au, Al, or alloys thereof, the material for the semitransparent metallic electrode layer (12T) includes Ag, Au, or alloys thereof; and wherein the thickness of the semitransparent metallic electrode layer, the combined thickness of the organic layers (14) and the transparent conductive phase-layer (20), and the placement of the light-emitting layer (14C) are selected so that each pixel in the display forms a tuned microcavity OLED device having an emission output efficiency above that of a comparable OLED device without the microcavity. |
