Display apparatus having substrate hole

A display apparatus, comprising:

• a substrate including a pixel area and a disconnected area which encloses a hole area;
• an organic light emitting diode in the pixel area;
• a plurality of organic insulating layers disposed below the organic light emitting diode;
• a plurality of inorganic insulating layers disposed below plurality of organic insulating layers;
• a disconnection structure which is disposed in the disconnected area and encloses the hole area;
• and
• an internal dam which is disposed in the disconnected area and encloses the disconnection structure,
• wherein the disconnection structure includes an eave portion constituting at least one of the plurality of organic insulating layers and a trench which is patterned by etching at least one of the plurality of inorganic insulating layers disposed below the eave portion,
• wherein the disconnection structure is configured to have a predetermined overhang and a predetermined depth by the eave portion and the trench, and
• wherein the eave portion has a mesa shape, a base of the eave portion directly contacts an upper surface of a topmost inorganic insulating layer among the plurality of inorganic insulating layers, and the base of the eave portion is wider than an upper portion of the eave portion.
