Abstract: A display device including: a first substrate; first through third subpixel electrodes which are disposed on the first substrate to neighbor each other; a second substrate opposing the first substrate; a first wavelength conversion pattern at least partially overlapping the first subpixel electrode and a second wavelength conversion pattern at least partially overlapping the second subpixel electrode; a first light transmission pattern at least partially overlapping the third subpixel electrode and a second light transmission pattern disposed between the first wavelength conversion pattern and the second wavelength conversion pattern; and a low refractive layer which has a lower refractive index than the first and second wavelength conversion patterns.
