Organic light emitting display device and method of repairing the same

A repairing method of an organic light emitting display device that includes a plurality of intersecting scan and data lines, organic emission layers connected to first switching elements, and first dummy lines between corresponding adjacent ones of the plurality of scan lines and parallel thereto, the method comprising:

• insulating a first switching element of an organic light emitting layer of a defective pixel from each other, the first switching element being connected to scan and data lines in a display area of a substrate;
• short-circuiting a first dummy line and the organic emission layer, the first dummy line being adjacent to the defective pixel;
• short-circuiting a second switching element and the first dummy line, the second switching element being disposed in parallel with the first switching element in a first direction, and the second switching element being in the non-display area adjacent to first ends of the first dummy lines;
• short-circuiting a second dummy line and the data line connected to the defective pixel, the second dummy line being adjacent to the first dummy line;
• and
• short-circuiting the second dummy line and a third dummy line, the second dummy lines being perpendicular to the first dummy lines and adjacent to the second switching elements.
