Display device using semiconductor light emitting device

A display device comprising:

• a substrate including an electrode;
• a plurality of semiconductor light emitting devices assembled on the substrate;
• and
• a color conversion part stacked on the plurality of semiconductor light emitting devices and converting a color,
• wherein the color conversion part includes:
• a porous layer;
• a wavelength conversion layer;
• and
• a reflective layer,
• wherein
• the wavelength conversion layer is disposed between the porous layer and the reflective layer,
• the porous layer is formed of an electro-polishable porous terminal,
• a surface of the reflective layer includes a first region and a second region surrounded by the first region,
• the second region has roughness higher than that of the first region, and
• a plurality of first protrusions are disposed in the second region, and
• wherein an adhesive member is provided between the porous layer of the color conversion part and one surface of the semiconductor light emitting device so that the color conversion part and the semiconductor light emitting device and be physically coupled.
