Abstract: A method of manufacturing a display apparatus includes: preparing a mother substrate; forming a concave portion, which comprises a first concave portion defined on a first surface of the mother substrate and a second concave portion defined on a second surface opposite to the first surface; reinforcing the mother substrate; and cutting the mother substrate in a lengthwise direction of the concave portion. A reinforcement thickness, which is a thickness of a reinforced part of a non-concave portion of the mother substrate from the first surface, is greater than half a value obtained by subtracting a depth of the first concave portion and a depth of the second concave portion, from a thickness of the non-concave portion of the mother substrate.
