Claim Text:
1. A manufacturing method of an organic light emitting diode (OLED) display, the manufacturing method comprising: forming a plurality of pixels and a plurality of thin film transistors electrically connected to the plurality of pixels, respectively, on a substrate; forming a first pixel defining layer dividing the plurality of pixels; detecting a defective pixel by testing the plurality of pixels; disconnecting an electrical connection between the defective pixel and a respective one of the thin film transistors; forming a connection wire for electrical connection between the defective pixel and a pixel adjacent to the defective pixel; and forming a second pixel defining layer on the first pixel defining layer to cover the connection wire, wherein: the pixels respectively include pixel electrodes and pixel terminals extended from the pixel electrodes, the thin film transistors are electrically connected with the pixel terminals, and forming the connection wire includes forming a connection hole by removing a portion of the first pixel defining layer to expose the defective pixel and the pixel terminal of the pixel that is adjacent to the defective pixel.
