1. An organic electroluminescent display device comprising:

  • a display area including a plurality of pixels;

    a peripheral area outside of the display area;

    a circuit layer including a circuit in the display area and another circuit in the peripheral area;

    a planarization film in the display area, the planarization film covering the circuit in the display area but not covering at least a portion of the circuit in the peripheral area;

    an inorganic insulating layer in the peripheral area, the inorganic insulating layer covering the at least a portion of the circuit in the peripheral area, the inorganic insulating layer surrounding an entire outer perimeter of the display area in a plan view; and

    a common electrode over the plurality of pixels in the display area, the common electrode including a peripheral portion in the peripheral area, the common electrode being in a higher layer than the planarization film and the inorganic insulating layer, whereinthe circuit layer includes, in the peripheral area, a wire, a contact portion, and a circuit element different from the contact portion, the contact portion being connected to the peripheral portion of the common electrode and connecting the wire and the common electrode, andthe contact portion is disposed farther from the display area than the different circuit element is from the display area.
