Abstract: An organic light-emitting display device and a method of fabricating the same are provided. The organic light emitting display device according to an example comprises a substrate including a pixel region including a plurality of red-subpixels, a plurality of green-subpixels, and a plurality of blue-subpixels, and a dummy pixel region including a plurality of dummy subpixels; a plurality of first bank layers disposed in the pixel region in a first direction and a second direction to define a plurality of subpixels; a plurality of second bank layers disposed on the first bank layers in the first direction in the pixel region to partition boundaries between a red-subpixel column, a green-subpixel column, and a blue-subpixel column; and an organic light-emitting element formed on each of the subpixels; and wherein at least one dummy subpixel forms a first dispensing region onto which an organic light-emitting material is dispensed.
