Abstract:
1. An organic light emitting display device, comprising: a substrate having a first pixel region, a second pixel region, and a third pixel region formed thereon; a first electrode formed in each of the first, second, and third pixel regions; a hole injection layer formed on the first electrodes and over an entire surface of the substrate; a first hole transport layer formed on the first electrode layer and the hole injection layer in the first pixel region, the second pixel region, and the third pixel region, and extending continuously therebetween; a second hole transport layer formed on the first hole transport layer in any two adjacent pixel regions among the first pixel region, the second pixel region, and the third pixel region, and extending continuously between the two adjacent pixel regions; a third hole transport layer formed on the second hole transport layer in any one region of the two adjacent pixel regions; a first organic emission layer formed on and in contact with the first hole transport layer; a second organic emission layer formed on and in contact with the second hole transport layer; a third organic emission layer formed on the third hole transport layer; and a second electrode formed on each of the first organic emission layer, the second organic emission layer, and the third organic emission layer.
