ABSTRACT:
An organic light emitting display device may include: a substrate having first, second and third pixel regions. A first electrode layer may be formed in each of the first, second and third pixel regions on the substrate. A hole injection layer may be formed over an entire surface of the substrate on the first electrode layers. A first hole transport layer may be formed on the first electrode layers in the first, second and third pixel region. A second hole transport layer may be formed on the first hole transport layer in any two adjacent pixel regions among the first, second and third pixel regions. A third hole transport layer may be formed on the second hole transport layer in any one of the two adjacent pixel region. A first, second and third organic emission layers may be formed on the first, second and third hole transport layer. A second electrode layer may be formed on the first, second and third organic emission layers. An OLED configured in this or a similar manner benefits from uniform operating characteristics and reducing tac time.
