Display apparatus and method of manufacturing the same

A method of manufacturing a display apparatus by performing a cutting process with reference to a cutting line on a mother substrate to thereby split the mother substrate into a plurality of display apparatuses, the plurality of display apparatuses including a display area comprising a plurality of pixels and a peripheral area outside the display area, the method comprising:

• forming a first insulating layer on the mother substrate;
• forming a first dam on the first insulating layer to surround the display area, a peripheral crack detection circuit electrically connected to at least one of the plurality of pixels, and a second dam arranged between the first dam and the cutting line, each in the peripheral area of each of the plurality of display apparatuses;
• and
• forming an encapsulation layer comprising a first inorganic layer, an organic layer, and a second inorganic layer in the display area and the peripheral area,
• wherein:
• the first inorganic layer and the second inorganic layer are formed on the cutting line of the mother substrate to extend over a peripheral areas of a display apparatus adjacent to the first inorganic layer and the second inorganic layer, and then, the first inorganic layer and the second inorganic layer are cut with reference to the cutting line in a process of cutting the mother substrate;
• and
• the peripheral crack detection circuit comprises a plurality of crack detection wires arranged on a same layer.
