Abstract
The present invention relates to a display device, and more particularly, to a display device using semiconductor light-emitting devices of several micrometers to tens of micrometers in size. The present invention provides a display device comprising: a base part; a plurality of assembly electrodes which is arranged on the base part and which generates an electric field when power is applied thereto; a dielectric layer formed to cover the assembly electrodes; and a plurality of semiconductor light-emitting devices arranged on the dielectric layer; wherein each of the semiconductor light-emitting devices comprises: a first assembly control layer formed at a portion of the whole area of one surface facing the dielectric layer; and a second assembly control layer formed at the other portion of the whole area of the one surface facing the dielectric layer, and made of a material different from that of the first assembly control layer.
