1. A method of fabricating a display device, the method comprising:
preparing a first substrate including a display area and a non-display area and a second substrate facing the first substrate;
bonding the first substrate to the second substrate via a sealing member; and
irradiating an intense light to the sealing member to form a fusion region having no physical boundary at the interface between the second substrate and the sealing member,
the sealing member including:
a first extension portion extending in a first direction along the non-display area;
a second extension portion extending in a second direction intersecting the first direction; and
a first corner portion connected to the first extension portion and the second extension portion, the first corner portion having a curvature; and
the fusion region provided between the second substrate and the sealing member,
wherein the fusion region is provided at least in the first corner portion of the sealing member,
wherein the fusion region is also disposed in the first extension portion and the second extension portion of the sealing member, and
wherein a plurality of fusion regions is spaced apart from each other in the first direction and the second direction.
