Abstract: An organic light emitting device includes a first substrate including a display area and a non-display area, and a dummy metal layer disposed on the first substrate in the non-display area. The dummy metal layer includes a first dummy metal layer and a second dummy metal layer that overlap each other. The organic light emitting device further includes an insulating layer disposed between the first dummy metal layer and the second dummy metal layer in a cross-sectional view, a second substrate covering the first substrate, and a sealant disposed between the first substrate and the second substrate and overlapping the dummy metal layer. The first dummy metal layer is electrically connected to the second dummy metal layer, and the sealant contacts the second dummy metal layer.
