Abstract

The present invention relates to a display device and, more particularly, to a transfer head for a semiconductor light-emitting device applied to the display device and a method for transferring a semiconductor light-emitting device. The transfer head for a semiconductor light-emitting device, according to the present invention, comprises: a base substrate; and an electrode unit disposed on the base substrate to generate an electrostatic force by charging an un-doped semiconductor layer of the semiconductor light-emitting device with electric charges, wherein the base substrate and the electrode unit are formed of light-transmitting materials so that at least a part of the semiconductor light-emitting device is viewable through the base substrate and the electrode unit in sequence.
