Abstract: An OLED display device includes a first substrate including a plurality of sub-pixels each including an emission area and a non-emission area; organic light emitting diodes on the first substrate; a second substrate opposed to the first substrate; a black matrix and a color filter layer on one side of the second substrate; a spacer on the black matrix and overlapping or parallel to one of the plurality of the gate lines and the plurality of data lines; and a film layer on the spacer, wherein an air gap is provided between the second substrate and the film layer, and a part of the film layer is exposed by the air gap.

Abstract: In an organic light emitting diode (OLED) display device and a method for fabricating the same, OLED pixels are patterned through a photolithography process, so a large area patterning can be performed and a fine pitch can be obtained, and an organic compound layer can be protected by forming a buffer layer of a metal oxide on an upper portion of the organic compound layer or patterning the organic compound layer by using a cathode as a mask, improving device efficiency. In addition, among red, green, and blue pixels, two pixels are patterned through a lift-off process and the other remaining one is deposited to be formed without patterning, the process can be simplified and efficiency can be increased.
