Summary: | A display device includes a display substrate including a light emitting element disposed on a first base substrate, and a color conversion substrate facing the display substrate. The color conversion substrate includes a second base substrate in which a first light transmitting area, a second light transmitting area, a third light transmitting area, and a light blocking area disposed between adjacent light transmitting areas are defined, a first bank disposed in the light blocking area on the second base substrate, a first low refractive index layer disposed between the second base substrate and the display substrate and covering the first bank, a first wavelength conversion pattern disposed in the first light transmitting area between the first low refractive index layer and the display substrate, a second wavelength conversion pattern disposed in the second light transmitting area between the first low refractive index layer and the display substrate, and a light transmission pattern disposed in the third light transmitting area between the first low refractive index layer and the display substrate. The first low refractive index layer has a refractive index lower than that of at least one of the first wavelength conversion pattern or the second wavelength conversion pattern. |
