Abstract: A light emitting display device includes a display panel including a first pixel group including a plurality of pixels in 2N rows. The light emitting display device further includes a second pixel group disposed subsequent to the first pixel group and including a plurality of pixels in 2N rows. The light emitting display device further includes an emission signal unit including a first emission stage for applying the same first emission signal to the first pixel group and a second emission stage for applying the same second emission signal to the second pixel group. In a first frame, a falling time of the first emission signal and a rising time of the second emission signal are different from each other.
