1. A display device comprising:
a color-converting part including a wavelength-converting particle configured to change a wavelength of an incident light to emit a light having a color different from the incident light;
a low refractive layer disposed on the color-converting part and having a refractive index smaller than a refractive index of the color-converting part;
a color filter pattern filtering the light emitted from the color-converting part; and
a light-reflective layer disposed between the color-converting part and the color filter pattern to selectively reflect a light having a wavelength same as the wavelength of the incident light.
