An organic light emitting display includes common coupling units at crossing regions of scan lines and data lines; first pixels at the crossing regions and positioned on an ith horizontal line to be coupled to the common coupling units positioned at the same crossing regions, wherein i is a positive integer; second pixels at the crossing regions and positioned on an (i+1)th horizontal line to be coupled to the common coupling units positioned at the same crossing regions; first control lines coupled to the first pixels; and second control lines coupled to the second pixels.
