Summary:The present invention relates to a device for removing a defective LED among a plurality of LEDs disposed on an LED substrate. The device for removing a defective LED comprises: a main stage in which an LED substrate is placed; a laser irradiation part for irradiating a laser with a defective LED placed on the LED substrate; an LED removal part placed between the LED substrate and the laser irradiation part, and adsorbing and removing the defective LED heated by the laser; and a flexible connection pipe connected between the laser irradiation part and the LED removal part to seal a space between the laser irradiation part and the LED removal part. According to the present invention, the device for removing a defective LED can reduce processing time and minimize thermal damage by using a laser as a heating source.
