Abstract: A light emitting display device includes multiple pixels arranged in multiple pixel rows, a first scan signal generator that provides a first scan signal to the pixels in the pixel rows, a second scan signal generator that provides a second scan signal to the pixels in the pixel rows, a third scan signal generator that provides a third scan signal to the pixels in the pixel rows, and a light emission signal generator that provides a light emission signal to the pixels in the pixel rows. Each of the second scan signal generator, the third scan signal generator, and the light emission signal generator provides a same signal to the pixels in two of the pixel rows.

Abstract: Provided is a light emitting display device comprising a driving transistor; a second transistor; a light emitting diode; a storage capacitor; a first scan line; and a driving gate electrode, in which a pixel includes only a transistor including an oxide semiconductor. The light emitting display device prevents deterioration of display quality due to a boost capacitor with a scan line in a pixel using an n-type transistor including an oxide semiconductor. Further, the light emitting display device prevents deterioration of display quality due to coupling with a data line in a pixel using an n-type transistor.
