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.

Organic light emitting diode display device and method of fabricating the same

Disclosed is a light emitting display device capable of minimizing a current driving capability deviation among driving switching elements. The light emitting display device includes pixels each including a first TFT for supplying data voltage to a first node in response to a scan signal, a second TFT for forming a current path between first and second nodes in response to an emission control signal, a driving TFT for forming a current path between a first driving voltage supply line and a third node in accordance with a voltage level of the second node, a third TFT for supplying a reference voltage to a fourth node in response to a sensing signal, a fourth TFT for supplying an initialization voltage to the third node in response to an initialization signal, and a fifth TFT for supplying the reference voltage to the second node in response to the initialization signal.
