The present invention relates to a light emitting device and a driving method thereof. The light emitting device comprises a plurality of data lines in a first direction, a plurality of scan lines in a second direction different from the first direction, and a plurality of sub-pixels formed on emitting areas that the data lines and the scan lines cross. A sub-pixel corresponding to a first outmost data line in the data lines emits a light having less brightness than a predetermined first brightness of the sub-pixel. The method of driving the light emitting device having a plurality of sub-pixels formed on emitting areas crossed by data lines and scan lines comprises changing first display data to second display data, and providing data currents corresponding to the second display data to the data lines. A data current provided to a first outmost data line in the data lines is less than a data current of a predetermined first gray scale. In the light emitting device and driving method thereof according to the present invention, a stripe pattern according to the sub-pixels corresponding to the outmost data lines does not appear since the gray scale of the sub-pixels corresponding to the outmost data lines is set up lower than a predetermined gray scale.
