Abstract:
An organic electroluminescence display device includes a p-doped layer doped with a P-type dopant on an anode electrode, a P-type dopant diffusion blocking layer on the p-doped layer, a first hole transport layer on the P-type dopant diffusion blocking layer, a light emitting layer on the first hole transport layer, an electron transport layer on light emitting layer, and a cathode electrode on the electron transport layer, the p-doped layer, the P-type dopant diffusion blocking layer, the hole transport layer, and the light emitting layer being stacked in the stated order on the anode.
