Abstract
Official abstract text for this publication.
A method of fabricating an organic light emitting diode display device having improved effective emitting area includes forming a first electrode over a substrate including a display region, which includes a plurality of pixel regions; forming the first bank on edges of the first electrode having a first width, and the second bank formed on the first bank having a second width smaller than the first width; forming an organic emitting layer on the first electrode and a portion of the first bank; and forming a second electrode on a organic emitting layer; patterning the second bank material layer to form a bank pattern; patterning the first bank using the bank pattern as an etching mask to form the first bank; and partially etching the bank pattern to form the second bank such that the first bank protrudes from the second bank by a third width.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of fabricating an organic light emitting diode display device, comprising: forming a first electrode over a substrate including a display region, which includes a plurality of pixel regions, the first electrode formed in each of the plurality of pixel regions; forming a first bank and a second bank, the first bank formed on edges of the first electrode and having a first width and a first thickness, and the second bank formed on the first bank and…
