Patent ID: 8349632

Claim:
A method of making an organic light-emitting display device, the method comprising: providing an intermediate device comprising an array of pixel regions, the array comprising first, second and third pixel regions, the array further comprising pixel definition layers partitioning the first, second and third pixel regions of the array; forming a first light-emitting layer over the first, second and third pixel regions, the first light-emitting layer comprising a first light-emitting material; forming a second light-emitting layer over the second and third pixel regions, the second light-emitting layer comprising a second light-emitting material differing from the first light-emitting material, wherein the second light-emitting layer does not extend over the first pixel region; and forming a third light-emitting layer over the third pixel region, the third light-emitting layer comprising a third light-emitting material differing from the first and second light-emitting materials, wherein the third light-emitting layer does not extend over the first and second pixel regions.
