Claim 22:
23. An organic light emitting display device comprising:
a substrate including an opening region, a peripheral region surrounding the opening region, and a display region surrounding the peripheral region, the substrate comprising a groove in the peripheral region and an opening in the opening region, the groove being formed inside the substrate in a depth direction of the substrate;
a light emitting structure in the display region on the substrate;
an undercut structure inside the groove in the substrate, the undercut structure comprising:
a sacrificial metal pattern having a first width; and
at least one insulating layer pattern having a second width greater than the first width; and

a functional module in the opening of the substrate,
wherein the substrate comprises:
a first organic film layer;
a first barrier layer on the first organic film layer;
a second organic film layer on the first barrier layer, the second organic film layer comprising a first opening in the peripheral region; and
a second barrier layer on the second organic film layer, the second barrier layer comprising a second opening overlapping the first opening,

wherein the at least one insulating layer pattern comprises:
a first insulating layer pattern on the sacrificial metal pattern; and
a second insulating layer pattern on the first insulating layer pattern,

wherein the first insulating layer pattern is located at a same layer as the second organic film layer, and the second insulating layer pattern is located at a same layer as the second barrier layer.
