Abstract
An organic light emitting diode display device and a method of fabricating the same, the method comprising: forming a first electrode on a substrate; forming a hydrophilic partition wall having a plurality of openings on the first electrode; forming hydrophobic red, green and blue organic light emitting layers on the plurality of openings of the partition wall, respectively; and forming a second electrode on each of the hydrophobic red, green and blue organic light emitting layers, whereby thin films can be selectively formed by a surface treatment so as to improve color impurity at boundaries of red, green and blue patterns.
