Display device with fusion region overlapping metal wiring

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.
