Claim 11:
12. A display device comprising:
a substrate comprising a light transmission region at which light is emitted from the display device, and a light blocking region which is adjacent to the light transmission region;
a first color filter pattern which is on the substrate and selectively transmits light of a first color;
a bank layer facing the substrate with the first color filter pattern therebetween;
in the light transmission region:
a first opening defined in the bank layer; and
a wavelength control pattern in the first opening of the bank layer;

in the light blocking region:
a second opening defined in the bank layer and spaced apart from the first opening; and
a filling structure in the second opening of the bank layer; and

a low refractive film in both of the light transmission region and the light blocking region, the low refractive film between the first color filter pattern and the bank layer and between the first color filter pattern and the wavelength control pattern,
wherein
each of the first opening and the second opening corresponds to the first color filter pattern,
each of the low refractive film and the wavelength control pattern has a refractive index,
the refractive index of the low refractive film is smaller than the refractive index of the wavelength control pattern, and
the low refractive film includes an organic material.
