Abstract:
Disclosed herein is an organic light emitting display device capable of stably compensating for a threshold voltage of a driving transistor. The organic light emitting display device according the present invention includes pixels, each for storing a voltage of a data signal in a storage capacitor through a first threshold voltage different from a second threshold voltage of a driving transistor for driving the pixel; scan lines and light emitting control lines respectively coupled to the pixels; and data lines for supplying the data signal to the pixels.
