摘要： A display device is provided. An embodiment of a display device includes a first substrate (11), a second substrate (21) disposed on the first substrate, first and second partition walls (PTL2, PTL3) disposed on the second substrate, the second partition wall (PTL3) being disposed outside the first partition wall (PTL2), a first trench disposed inside the first partition wall and having a first width (W1), a second trench (TR3) disposed between the first and second partition walls and having a second width greater (W2) than the first width; an alignment key (AK) disposed to overlap the second trench; a first spacer (CS3) disposed on the alignment key, and a sealing member (50) disposed along an edge between the first substrate (11) and the second substrate (21) without overlapping the alignment key (AK), wherein the first spacer (CS3) partially overlaps the first partition wall (PTL2), the second partition wall (PTL3), and the sealing member (50).

摘要： 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.

摘要： A display device includes a first display substrate including a light emitting element which emits light of a first color or light of a second color different from the first color, a second display substrate including in order toward the first display substrate, a layer including both a bank layer defining an opening and a wavelength control pattern in the opening, a capping layer covering the wavelength control pattern and the bank layer, and a color absorbing layer which corresponds to the bank layer and blocks the light of the first color and the light of the second color. The capping layer includes a first area corresponding to the color absorbing layer, the bank layer includes a second area corresponding to the color absorbing layer, and the first area of the capping layer is between the color absorbing layer and the second area of the bank layer.

摘要： A display device includes a pixel; and a first color conversion region, a second color conversion region, and a third color conversion region respectively overlapping a first color pixel, a second color pixel, and a third color pixel and spaced from each other. The third color conversion region is aligned with a region between the first color conversion region and the second color conversion region in a first direction, and the first color conversion region and the second color conversion region are aligned with each other in a second direction crossing the first direction. Part of the first color conversion region is disposed in a second pixel area that is adjacent to the first pixel area in the second direction, and part of the second color conversion region is positioned in a third pixel area that is adjacent to the first pixel area in the second direction.
