Claim Text:
1. An organic light emitting display device comprising: a substrate in which at least three pixel areas are defined; a first electrode formed all over the substrate; a hole transporting layer formed on the first electrode; a first light-emitting material layer formed on the hole transporting layer at a position corresponding to a first pixel area; a second light-emitting material layer formed on the hole transporting layer at a position corresponding to a second pixel area; a third light-emitting material layer formed on the hole transporting layer at a position corresponding to a third pixel area; an electron transporting layer formed on the first light-emitting material layer, the second light-emitting material layer, and the third light-emitting material layer; a first optical assistant transporting layer disposed between the hole transporting layer and the first light-emitting material layer; a second optical assistant transporting layer disposed between the second light-emitting material layer and the electron transporting layer, the second light-emitting material layer disposed between and in direct contact with the second optical assistant transporting layer and the hole transporting layer; and a second electrode formed on the electron transporting layer.
