1. A stereoscopic image display device comprising:

  • a display panel comprising a plurality of pixels configured to emit light according to stored data voltages during corresponding sub-frames of a corresponding frame;

    a scan driver for transmitting scan signals to the pixels;

    a gate driver for transmitting an initialization control signal, a compensation control signal, and an emission control signal to the pixels;

    a data driver for transmitting first image data signals and second image data signals, which correspond to a different view point from that of the first image data signals, to the pixels; and

    a controller for controlling operation of the scan driver, the gate driver, and the data driver, and for generating and transmitting the first image data signals and the second image data signals according to an external image signal,wherein the corresponding sub-frames comprise a first sub-frame that comprises;

    a first period for initializing the stored data voltages of the pixels that correspond to third image data signals transmitted in a previous sub-frame of a previous frame to an initialization voltage;

    a second period for changing the stored data voltages of the pixels to correspond to the first image data signals written in the previous sub-frame for light emission in the first sub-frame and for compensating a threshold voltage of a driving transistor of each pixel;

    a third period for sequentially writing second data voltages, which correspond to the second image data signals of a second sub-frame of the corresponding frame, to the pixels; and

    a fourth period, configured to be concurrent with and as long as or longer than the third period, for emitting light from the pixels according to the stored data voltages that correspond to the first data signals.
