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 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 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.
