Abstract: A light conversion substrate includes a first substrate having a first region, a second region, and a third region. A first light conversion pattern is disposed on the first region and includes first wavelength conversion particles. A second light conversion pattern is disposed on the second region and is spaced apart from the first light conversion pattern and includes second wavelength conversion particles. A first scattering pattern is disposed on the third region to fill a space between the first light conversion pattern and the second light conversion pattern and includes first scattering particles. The first scattering pattern overlaps a portion of the first light conversion pattern and a portion of the second light conversion pattern in a direction of the thickness of the first substrate.

Abstract: 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.

Abstract: A display device that includes a plurality of pixels arranged in a row direction and a column direction crossing the row direction. The display device includes a first substrate including light-emitting elements each disposed in the respective pixels. A second substrate faces the first substrate. A plurality of optical patterns are disposed on the second substrate in pixel columns, respectively, and extend along the column direction. Light-blocking patterns are disposed on the second substrate. The light-blocking patterns include a main light-blocking pattern extending along pixel column boundaries and fill spaces between adjacent optical patterns, and a subsidiary light-blocking pattern disposed on the optical patterns at pixel row boundaries and having a thickness smaller than a thickness of the main light-blocking pattern.

Abstract: A display device includes a first light emitting element on a first substrate and overlapping a first effective pixel area; test light emitting elements on the first substrate and overlapping the test pixel area; a first color filter on a second substrate and overlapping the first light emitting element; a first wavelength conversion pattern on the first color filter and overlapping the first color filter and the first light emitting element; a first test color filter on the second substrate and overlapping one of the test light emitting elements; and a first test wavelength conversion pattern on the second substrate and overlapping another one of the test light emitting elements. The first test wavelength conversion pattern and the first wavelength conversion pattern include a same first wavelength conversion material, and the first test color filter and the first color filter include a same first color colorant.

Abstract: A liquid-crystal display device and a method of manufacturing a liquid-crystal display device. The liquid-crystal display device has a display area and a non-display area surrounding the display area defined therein, and the device includes: a first substrate; a second substrate disposed above the first substrate; and a liquid-crystal layer interposed between the first substrate and the second substrate. The first substrate includes a first base substrate, a first wavelength band filter disposed on the first base substrate in the non-display area, and a second wavelength band filter disposed on the first base substrate in the display area.
