1. An organic electroluminescent display device, comprising:

  • an array substrate including a driving thin film transistor in a pixel region on a first substrate;

    an opposing substrate including an organic electroluminescent diode in the pixel region on a second substrate;

    a separator corresponding to a boundary of the pixel region on the opposing substrate;

    an adhesive layer filling a space between the array substrate and the opposing substrate, the adhesive layer including conductive particles;

    a connection spacer configured to electrically connect the organic electroluminescent diode with the driving thin film transistor such that the adhesive layer disposes between the driving thin film transistor and the organic organic electroluminescent diode;

    at least one first shield pattern on one of an inner surface of the array substrate and an inner surface of the opposing substrate, the at least one first shield pattern surrounding the display region of the device; and

    at least one second shield pattern on the other of the inner surface of the array substrate and the inner surface of the opposing substrate, the at least one second shield pattern surrounding the display region of the device and alternating with the first shield pattern,wherein the first pattern and the second pattern occlude,wherein each of the first shield pattern and the second shield pattern has a first width equal to each other,wherein a distance between a neighboring two of the first shield patterns or a neighboring two of the second shield patterns has a second width equal to each other,wherein the second width is bigger than the first width, andwherein the second shield pattern comprises a same material as the connection spacer.
