Claim 0:
1. 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;
a semiconductor element between the substrate and the light emitting structure;
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 groove extends in the depth direction of the substrate lower than the semiconductor element.
