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 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.
