Claim Text:
1. A transparent organic light emitting display device comprising: a first substrate having a plurality of pixel regions, each pixel region including an emissive area configured to form an image and a transmissive area configured to pass through an external light; a thin film transistor (TFT) disposed in the emissive area; an organic light emitting element disposed in the emissive area, the organic light emitting element being electrically connected to the TFT disposed in the emissive area; a plurality of insulating layers in the emissive area, wherein at least one of the plurality of insulating layers is extended into the transmissive area and at least a part of the insulating layer being extended into the transmissive area has substantially the same refractive index as the first substrate; and a plurality of banks, wherein each pixel region includes a first bank and a second bank from the plurality of banks, the first bank dividing the emissive area and the transmissive area of the pixel region, and the second bank dividing the pixel region from an adjacent pixel region, and wherein the transmissive area of each pixel region located between the first bank and the second bank passes through the external light.
