Abstract
The present invention relates to a transfer head for a micro LED, the transfer head gripping a micro LED and transferring the micro LED to a display substrate. In particular, the present invention relates to a transfer head for a micro LED, the transfer head gripping a micro LED in a state where a grip surface of the transfer head and an upper surface of the micro LED are not in contact with each other when transferring the micro LED. Accordingly, it is possible to prevent positional error which may occur when transferring the micro LED and prevent damage of the micro LED.
