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 substrate including an alignment area in a non-display area, and a display area including a plurality of material layers on the substrate; in the alignment area, a plurality of keys including a first alignment key and a second alignment key. Each alignment key includes a light blocking pattern, a layer pattern and a display pattern. The position of the display pattern within the first alignment key is different from the position of the display pattern within the second alignment key, the layer pattern of the alignment key and one material layer among the plurality of material layers are respective portions of a same material layer on the substrate, and the layer pattern of the first alignment key and the layer pattern of the second alignment key are respective portions of different material layers among the plurality of material layers on the substrate.

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.
