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.
