Patent ID: 8517787

Claim:
A method of manufacturing an organic electro-luminescence display device, the method comprising: providing a substrate; forming a first electrode patterned by a subpixel unit on the substrate; forming a subpixel separating pattern on portions of the substrate that correspond to an edge and a periphery of the first electrode; sequentially forming a first charge transport layer, an organic emission layer, and a second charge transport layer to cover the first electrode, the second charge transport layer having an insoluble material for preventing dissolution by a material forming the first charge transport layer; patterning the first charge transport layer, the organic emission layer, and the second charge transport layer by the subpixel unit to form a first charge transport pattern, an organic emission pattern, and a second charge transport pattern located on the first electrode; and forming a second electrode on the second charge transport pattern, wherein the forming of the first charge transport layer, the organic emission pattern, and the second charge transport layer comprises: forming a photoresist layer on the second charge transport layer; patterning the photoresist layer to form a photoresist pattern on the second charge transport layer; and etching the first charge transport layer, the organic emission layer, and the second charge transport layer using the photoresist pattern as an etch mask.
