Abstract: An organic light emitting display device is provided as follows. A first thin film transistor having a first semiconductor pattern is disposed on a substrate. A second thin film transistor having a second semiconductor pattern is disposed on the substrate. An insulating layer covers the first thin film transistor and the second thin film transistor. At least one first dummy hole passing through the insulating layer overlaps the first semiconductor pattern of the first thin film transistor. At least one second dummy hole passing through the insulating layer overlaps the second semiconductor pattern of the second thin film transistor. Numbers or sizes of the at least one first dummy hole and the at least one second dummy hole are different from each other.
