An organic light emitting display device includes a substrate comprising a major surface; a display region and a peripheral region surrounding the display region when viewed in a viewing direction perpendicular to the major surface; an array of a plurality of pixels disposed in the display region; and a first power line extending from the peripheral region into the display region, the first power line being electrically connected to the array of pixels at a contact point in the display region. When viewed in the viewing direction, the first power line includes: a first extension extending from the peripheral region to the display region; and a second extension connected to the first extension; and a third extension connected to the second extension and extending from a location in the display region toward the peripheral region.
