Zusammenfassung:	A micro-LED display device and a manufacturing method thereof are disclosed. The method comprises: forming micro-LEDs (202) on a carrier substrate (201), wherein the carrier substrate (201) is transparent for a laser which is used in laser lifting-off; filling trenches between the micro-LEDs (202) on the carrier substrate (201) with a holding material (209); performing a laser lifting-off on selected ones of the micro-LEDs (202) to lift off them from the carrier substrate (201), wherein the selected micro-LEDs (202) are held on the carrier substrate (201) through the holding material (209); bonding the selected micro-LEDs (202) onto a receiving substrate (207) of the micro-LED display device; separating the selected micro-LEDs (202) from the carrier substrate (201) to transfer them to the receiving substrate (207).
