Abstract:
1. An organic electroluminescence display device, comprising: a base substrate; a multilayer laminate formed on the base substrate, the multilayer laminate comprising a lower electrode layer, an organic electroluminescence layer and an upper electrode layer; and the multilayer laminate having a broken surface, the broken surface containing a cavernous-shaped broken portion having a cavity comprising: a protective layer formed on the multilayer laminate, wherein the crater, the overhang protrusion and the broken surface each have a form and shape resulting from an explosion of a portion of the organic electroluminescence layer contained in the multilayer laminate, and wherein the protective layer is an ultra-thin film completely covering the broken surface of the multilayer laminate including the cavity of the cavernous-shaped broken portion and preventing the broken surface from contacting the outside air.
