Abstract: Disclosed is an electroluminescent display apparatus. The electroluminescent display apparatus includes a partition provided to define an emission area on a first substrate, a light emitting layer provided in the emission area, an electrode provided on the light emitting layer; and an organic cover layer provided on the electrode. The organic cover layer includes hexaazatriphenylene hexacarbonitrile. The organic cover layer including hexaazatriphenylene hexacarbonitrile is provided on the electrode, and, thus, in a process of forming the organic cover layer, the occurrence of foreign materials is reduced, and cracks are prevented from occurring in the organic cover layer when the foreign materials are pressed.
