Organic light emitting display device and method of manufacturing the same

摘要

An organic light emitting display device includes a substrate and a plurality of pixels defined in the substrate. A pixel includes red subpixel, green subpixel, blue subpixel, and white subpixel. The organic light emitting display device includes an anode electrode formed on the substrate, a cathode electrode opposing the anode electrode, and a red common emission layer, a green common emission layer, and a blue common emission layer formed across each of the red, green, blue and white subpixel areas. The blue common emission layer is disposed above and adjacent to the anode electrode, the green common emission layer is disposed above the blue common emission layer, and the red common emission layer is disposed above the green common emission layer and adjacent to the cathode electrode.

1. An organic light emitting display device, comprising:
a substrate; and a plurality of pixels defined in the substrate, a pixel including a red subpixel, a green subpixel, a blue subpixel, and a white subpixel, each of the red subpixel, the green subpixel, the blue subpixel, and the white subpixel comprising: a first electrode on the substrate; a blue common layer on the first electrode; a green common layer on the blue common layer; a red common layer on the green common layer; and a second electrode on the red common layer,
wherein at least one of the subpixels include a hole transporting layer or an electron transporting layer between the blue common layer and the green common layer or between the green common layer and the red common layer,wherein the number of the electron transporting layers in each of the green subpixel and the blue subpixel is greater than in the red subpixel.
