1. A method of bonding a display device, comprising:
providing a first layer on a fixed stage, wherein the first layer comprises a first flat portion and first bending portions, which are curvedly extended from opposite side portions of the first flat portion, respectively;
providing a second layer below a pressing part disposed over the fixed stage, wherein the second layer comprises a second flat portion and second bending portions, which are curvedly extended from opposite side portions of the second flat portion, respectively;
moving the pressing part in a downward direction to bond the second flat portion to the first flat portion; and
pressing the second bending portions toward the first bending portions to bond the second bending portions to the first bending portions,
wherein, before the bonding of the second bending portions to the first bending portions, the first and second bending portions are disposed between the fixed stage and the pressing part, in a state bent with curvatures, respectively, and the curvature of a lower surface of each of the second bending portions is smaller than the curvature of an upper surface of each of the first bending portions, and
wherein, before the bonding of the second bending portions to the first bending portions, an entirety of the lower surface of the first bending portion is in contact with the fixed stage.
