Abstract: A multi-panel organic light emitting display device is disclosed that includes a plurality of display panels coupled to each other. Each of the plurality of display panels includes: a substrate including an active area and a non-active area; and a display unit including an organic light emitting element on the substrate. Each of the plurality of display panels also includes: a plurality of signal lines disposed on the substrate and electrically connected to the display unit; and a plurality of link lines disposed under the substrate. Each of the plurality of display panels further includes a plurality of side lines connecting the plurality of signal lines and the plurality of link lines. Each of the plurality of display panels also includes a driving circuit electrically connected to the plurality of link lines.
