Abstract: A pixel includes a driving circuit, a first organic light emitting diode, a second organic light emitting diode, and a self-repair circuit. The driving circuit supplies current based on a data signal supplied through a data line. The first organic light emitting diode is coupled to the driving circuit through a first current path. The second OLED is coupled to the driving circuit through a second current path. The self-repair circuit interrupts the first current path and supplies the current to the second current path when the first organic light emitting diode has a defect.
