Abstract
An organic light emitting display device includes a thin film transistor on a substrate including a display area having an inner light-emitting area and an outer light-emitting area and a peripheral area, a first conductive member connected to the thin film transistor, a first via insulation layer covering the first conductive member, a second conductive member on the first via insulation layer to overlap the outer light-emitting area and a part of the peripheral area, a second via insulation layer covering the second conductive member, a first electrode on the second via insulation layer to overlap the display area and a part of the peripheral area, an organic light emitting layer on the first electrode, and a second electrode on the organic light emitting layer. The second via insulation layer and the first electrode have a step structure between the inner and outer light-emitting areas.
