Abstract:
An organic electroluminescent (EL) display device having a plurality of pixel circuits formed at crossing points of a plurality of scan lines and a plurality of data lines is provided. Each pixel circuit includes at least two driving transistors connected to a first power voltage line, the at least two driving transistors receiving a data signal through at least one of the data lines and outputting a driving current corresponding to the data signal; and an organic light emitting diode having at least two first electrodes respectively connected to the at least two driving transistors and emitting a light corresponding to the driving current. The organic light emitting diode has the at least two first electrodes and a common second electrode per pixel in order to prevent the whole pixel from not operating due to a short circuit occurring between one of the first electrodes and the second electrode.
