An organic light-emitting display includes first sub-pixels of a first color and second sub-pixels of a second color. Pairs of the first sub-pixels are consecutively arranged in different rows, and pairs of the second sub-pixels are consecutively arranged in different rows. The pairs of first sub-pixels and the pairs of second sub-pixels arranged alternately in a first column, and third sub-pixels are in a second column adjacent to the first column. When one sub-pixel is defective, a control circuit provides current another sub-pixel of the same color.
