Abstract: A display device includes a display substrate and a color conversion substrate. The color conversion substrate includes: a second base substrate in which first to third light transmitting areas, and a light blocking area between adjacent light transmitting areas are defined, a first bank in the light blocking area, a first low refractive index layer between the second base substrate and the display substrate and covering the first bank. The color conversion substrate further includes a first wavelength conversion pattern in the first light transmitting area, a second wavelength conversion pattern in the second light transmitting area, and a light transmission pattern in the third light transmitting area, which are between the first low refractive index layer and the display substrate. The first low refractive index layer has a refractive index lower than at least one of the first wavelength conversion pattern or the second wavelength conversion pattern.

Abstract: A display device includes a first base portion in which a first emission area and a non-emission area are defined, a first light emitting element on the first base portion and overlapping the first emission area, a thin film encapsulation layer on the first light emitting element, a second base portion on the thin film encapsulation layer, a first color filter on the second base portion and overlapping the first emission area, a first wavelength conversion pattern on the first color filter and overlapping the first emission area, and a first optical pattern between the first color filter and the first wavelength conversion pattern and overlapping the first emission area. A refractive index of the first optical pattern is smaller than that of the first wavelength conversion pattern, and one surface of the first optical pattern facing the first wavelength conversion pattern is concave toward the second base portion.
