An organic lighting emitting display device and a driving method thereof are provided to decrease the number of light emitting control lines by adjusting the light emitting periods of respective sub-pixels. An organic lighting emitting display device includes a first pixel circuit and first and second light emitting control lines. The first pixel circuit includes first to third OLEDs(OLED_R,OLED_G,OLED_B), first to third driving transistors(MR1,MG1,MB1), and first to third switches. The driving transistors deliver driving currents to the respective OLEDs. The first switch(SR) is connected between a first electrode of the first OLED and a first electrode of the first driving transistor. The second switch(SG) is connected between a first electrode of the second OLED and a first electrode of the second driving transistor. The third switch(SB1,SB2) is connected between a first electrode of the third OLED(Organic Light Emitting Device) and a first electrode of the third driving transistor. The second light emitting control line is connected to a second pixel circuit.
