Abstract: The present invention relates to a display device, and more particularly, to a display device using a semiconductor light-emitting diode. The display device according to the present invention comprises: a substrate having a wiring electrode formed thereon; a plurality of semiconductor light-emitting diodes electrically connected to the wiring electrode; an insulating layer provided to fill space between the semiconductor light-emitting diodes; a polarizing filter layer which is overlapped on the insulating layer and filters light incident into a specific direction; and a wavelength conversion layer which is overlapped on the polarizing filter layer and provided to convert the wavelength of light.
