A method for repairing an organic light emitting display having a plurality of unit pixels each including a white subpixel is provided. The method includes detecting a defective white subpixel by checking circuit units of the white subpixels, connecting a circuit unit of a neighboring subpixel positioned adjacent to the defective white subpixel in the unit pixel with a light emitting unit of the defective white subpixel using a repair conductive pattern, storing a repair position to which the repair conductive pattern is connected, and compensating for digital video data that will be input to the repair position.
