Abstract
The present disclosure discloses an organic light emitting display device having a substrate including an active area configured to display an image and an inactive area configured to surround the active area; a power supply line in the inactive area; a first planarization layer on a layer where the power supply line is disposed on; a first metal layer on the first planarization layer and in contact with the power supply line; a second planarization layer configured to planarize an upper portion of the first metal layer; and a second metal layer, on the second planarization layer, and in contact with the first metal layer and a cathode of an organic light emitting diode, so that an improved arrangement of signals lines in the inactive area where conductive lines are efficiently arranged in a limited space at an edge portion of the substrate in order to realize a narrow bezel configuration and have a signal line structure capable of supplying stable power to various components.
