    摘要： A color conversion substrate includes: a base part in which a first light-transmitting area and a second light-transmitting area are defined; a first stack disposed on the base part and a second stack disposed on the first stack; a first wavelength conversion pattern overlapping the second light-transmitting area, and disposed on the second stack, where the first wavelength conversion pattern converts light of a first color into light of a second color; and a light-transmitting pattern overlapping the first light-transmitting area and disposed between the first stack and the second stack, where portions of the first stack and the second stack in the second light-transmitting area are in direct contact with each other to constitute a blue light reflective layer.

    摘要： A display device includes a first substrate including a first emission area emitting light of a first color, a second emission area emitting light of a second color having a peak wavelength shorter than a peak wavelength of light of the first color, and a light blocking area which blocks light; a color filter layer disposed on a surface of the first substrate; and a wavelength control layer disposed on the color filter layer and including a bank layer and a wavelength control structure. The bank layer is disposed in the light blocking area on the color filter layer. The wavelength control structure is disposed in a first opening and the second opening of the bank layer. The first opening, the second opening, and the bank hole are spaced apart from each other. The bank hole surrounds an edge of the first opening.

    摘要： A liquid crystal display (“LCD”) device includes: a first substrate having a first area that allows an image to be transmitted therethrough and a second area that blocks an image; a second substrate opposite to the first substrate; a liquid crystal layer between the first substrate and the second substrate; and a polarizing layer on the second substrate. The polarizing layer may include first polarizing patterns and second polarizing patterns, wherein, in a planar view, the first polarizing patterns overlap with the first area and the second polarizing patterns overlap with the second area.

    摘要： 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.

    摘要： 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.
