Abstract

An organic light emitting display device (OLED) includes a transparent substrate a first electrode formed on the transparent substrate a partition wall including first and second tapered structures having different tapers and formed on the first electrode, and an organic light emitting layer stacked on both sides of the first electrode below a level of the partition wall and a second electrode. The OLED device is manufactured by, for example, forming a first electrode on a transparent substrate, forming a partition wall having first and second tapered structures on the first electrode, and forming an organic light emitting layer and a second electrode, sequentially, on both sides of the first electrode below a level of the partition wall.

First claim

What is claimed is:

1. A method for fabricating an OLED, comprising:
providing a transparent substrate;
forming a first electrode on the transparent substrate;
forming a first silicon nitride film and a second silicon nitride film on the first electrode, wherein the second silicon nitride film is thicker than the first silicon nitride film;
etching the first silicon nitride film and the second silicon nitride film by a dry etching process to form a partition wall including a…
