A method of transferring micro devices is provided. A carrier substrate including a buffer layer and a plurality of micro devices is provided. The buffer layer is located between the carrier substrate and the micro devices. The micro devices are separated from one another and positioned on the carrier substrate through the buffer layer. A receiving substrate contacts the micro devices disposed on the carrier substrate. A temperature of at least one of the carrier substrate and the receiving substrate is changed after the micro devices contact the receiving substrate. At least a portion of the micro devices are transferred from the carrier substrate onto the receiving substrate after changing the temperature of at least one of the carrier substrate and the receiving substrate.
