Patent ID: 8441420

Claim:
An organic electroluminescent (EL) display device having a plurality of pixel circuits at crossing points of a plurality of scan lines and a plurality of data lines, each of the pixel circuits comprising: at least two driving transistors connected to a first power voltage line, the at least two driving transistors for receiving a data signal through at least one of the data lines and outputting a driving current corresponding to the data signal; and a single organic light emitting diode comprising at least two first electrodes having symmetrical shapes different from each other and a same organic emission layer on the at least two first electrodes, the organic emission layer having at least two separate light emitting areas and the at least two first electrodes being respectively connected to the at least two driving transistors, and the single organic light emitting diode being for emitting a light corresponding to the driving current, wherein each of the at least two first electrodes corresponds to a corresponding one of the at least two separate light emitting areas, and the at least two separate light emitting areas emit the light in substantially the same direction, and wherein the at least two separate light emitting areas have substantially the same size.
