Organic electroluminescence display device and method for manufacturing the same

A method for manufacturing an organic electroluminescence display device which comprises:

• 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
• a protective layer comprising an ultra-thin film formed on the multilayer laminate,
• wherein the multilayer laminate contains a cavernous-shaped broken portion including a cavity, the cavity including:
• a crater contained within the multilayer laminate and free from at least a portion of the organic electroluminescence layer and the upper electrode layer contained in remaining portions of the multilayer laminate, and
• an overhang protrusion extending above and covering at least a portion of the crater and containing a displaced portion of the organic electroluminescence layer and the upper electrode layer of the multilayer laminate, and
• a broken surface of the multilayer laminate,
• the method comprising the steps of:
• forming the multilayer laminate on the base substrate;
• exploding a portion of the organic electroluminescence layer contained in the multilayer laminate and forming the crater, the overhang protrusion and the broken surface of the multilayer laminate;
• and
• completely covering the broken surface of the multilayer laminate in the cavity of the cavernous-shaped broken portion with the ultra-thin film of the protective layer and forming a barrier between the broken surface of the multilayer laminate in the cavity of the cavernous-shaped broken portion and outside air.
