An organic electroluminescence display device is provided to prevent the degradation of white balance property due to the luminance nonuniformity of pixels for each color by installing capacitors with different capacities in each pixel according to the colors. An organic electroluminescence display device includes pixel circuits formed in each pixel; a data driving unit electrically connected with each pixel circuit through a data signal line; and a scan driving unit outputting a selection signal(S[n]) and a first control signal(E[n]) to each pixel circuit. The pixel circuit comprises an organic electroluminescent device(OLED) emitting the light correspondingly to the current; a first transistor(M1) feeding driving current to the organic electroluminescent device; a first capacitor(C1) storing voltage corresponding to the driving current; and a second capacitor(C2) varying the potential of a main electrode of the first transistor according to the voltage level variation of the signal applied to one end. The capacities of at least one of the first and second capacitors are different according to each pixel.
