    Abstract: An organic light emitting display apparatus and an electronic device including the same are provided. The organic light emitting display apparatus comprises an organic light emitting display panel including a display area and a non-display area, the display area including a transparent area, a buffer area provided outside the transparent area, and an opaque area provided outside the buffer area, a camera provided in the transparent area in a rear surface of the organic light emitting display panel to photograph a region in a forward direction with respect to the organic light emitting display panel, and a transparent area pixel driving circuit provided in the buffer area to drive a transparent area organic light emitting diode provided in the transparent area. The transparent area organic light emitting diode is connected to the transparent area pixel driving circuit through a transparent area electrode line.

    Abstract: Disclosed is an organic light emitting display device that may include first and second pads on a pad area of a substrate, wherein the first pad includes a first bonding region and a first link region, and the second pad includes a second bonding region, a contact region, and a second link region. A first bonding electrode in the first bonding region is electrically connected to one or more signal lines in the active area of the device through contact holes in the first bonding region. A second bonding electrode is electrically connected to one or more signal lines of the device through contact holes in the contact region. The contact region is closer to the active area than the first bonding region.
