Organic light emitting diode display and method for manufacturing the same

A display device comprising:

• a substrate;
• a light emitting unit disposed on the substrate;
• a first inorganic layer disposed on the substrate and covering the light emitting unit, wherein two opposite horizontal edge portions of the first inorganic layer are disposed on the substrate;
• a first organic layer disposed on the first inorganic layer and covering a smaller area than the first inorganic layer;
• a second inorganic layer disposed on the first inorganic layer and contacting the first inorganic layer at an edge of the second inorganic layer;
• a second organic layer disposed on the second inorganic layer and covering a smaller area than the second inorganic layer;
• and
• a third inorganic layer disposed on the organic layer, covering a larger area than the organic layer and contacting the second inorganic layer at vertical and horizontal edge portions of the third inorganic layer,
• wherein the second organic layer covers an area that is the same as the first organic layer.

A display device comprising:

• a substrate;
• a light emitting unit on the substrate;
• a first inorganic layer disposed on the substrate, and directly disposed on and covering the light emitting unit;
• a second inorganic layer disposed on the first inorganic layer and contacting the first inorganic layer at an edge of the second inorganic layer, the second inorganic layer entirely and directly contacting the first inorganic layer;
• an organic layer disposed on the second inorganic layer and covering a smaller area than the second inorganic layer;
• and
• a third inorganic layer disposed on the organic layer, covering a larger area than the organic layer and contacting the second inorganic layer at vertical and horizontal edge portions of the third inorganic layer.

A display device, comprising:

• a substrate;
• a light emitting unit disposed on the substrate;
• a metal oxide layer directly disposed on the light emitting unit;
• a first inorganic layer disposed on the substrate and covering the light emitting unit and the metal oxide layer;
• an intermediate layer disposed on the first inorganic layer and covering an area smaller than the first inorganic layer;
• a second inorganic layer disposed on the first inorganic layer and the intermediate layer and contacting the first inorganic layer at an edge thereof while covering a larger area than the intermediate layer;
• and
• a third inorganic layer disposed on the second inorganic layer and contacting the second inorganic layer at vertical and horizontal edge portions thereof,
• wherein the intermediate layer comprises an organic layer or a multilayer structure comprising an organic layer and a metal oxide layer.
