摘要： An electroluminescent display device includes a display part configured to display an image. Also, the electroluminescent display device includes an encapsulation unit disposed over the display part and a heat dissipation sheet disposed over the encapsulation unit. The encapsulation unit includes a sealing member composed of a first adhesive layer, a second adhesive layer, and a barrier layer between the first adhesive layer and the second adhesive layer. Further, the encapsulation unit includes a hole in the second adhesive layer and the barrier layer. A side surface of the barrier layer may be electrically connected to the heat dissipation sheet through a conductive paste injected into the hole. Thus, it is possible to improve electromagnetic interference.
