Abstract: A display device is provided. An embodiment of a display device includes a first substrate, a second substrate disposed on the first substrate, first and second partition walls disposed on the second substrate, the second partition wall being disposed outside the first partition wall, a first trench disposed inside the first partition wall and having a first width, a second trench disposed between the first and second partition walls and having a second width greater than the first width; an alignment key disposed to overlap the second trench; a first spacer disposed on the alignment key, and a sealing member disposed along an edge between the first substrate and the second substrate without overlapping the alignment key, wherein the first spacer partially overlaps the first partition wall, the second partition wall, and the sealing member.

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.
